The GDI engine-powered CARISMA will be unveiled by Mitsubishi Motors Corporation at the 58th Frankfurt Motor Show, which takes place from September 9 through September 21. The GDI CARISMA will be the first GDI engine-powered vehicle to be introduced outside of Japan when it goes on sale in European markets commencing in October in Germany.
In September 1995, the Frankfurt Motor Show hosted the GDI (gasoline direct injection) engine’s European debut, where it sparked a lot of attention. After the event, the GDI engine won the praise of politicians, journalists, and automobile owners all around Europe, where there is a great deal of worry about global warming brought on by carbon dioxide. Its release onto the market was eagerly anticipated.
The business intends to launch other GDI-powered European export models beginning next year, with the GDI CARISMA guiding the way.
The new CARISMA series has various improvements to the appearance and interior trim to go along with the inclusion of the GDI engine and other updates to the engine lineup.
The GDI engine now powers all 1.8-liter versions. Continued are the 1.6-liter gasoline and 1.9-liter diesel engines.
The GALANT/LEGNUM series, which debuted in Japan in August of last year, employed a power plant similar to the GDI engine. The catalytic converter has been modified to meet with European rules and regulations, and the low-end and mid-range torque has been increased to match the power output characteristics to the demands of the European market. In comparison to its 1.8-liter port-injection predecessor, the GDI engine achieves roughly 20% greater fuel economy, 10% more power, and 20% lower carbon dioxide emissions.
The Netherlands Car B.V. (NedCar), a partnership between Mitsubishi Motors, the Swedish Volvo Car Corporation, and the Dutch government, manufactures CARISMA. Beginning in June 1995, the 5-door hatchback variant went into production. In August 1996, variants with diesel engines and a 4-door version were added to the inventory. In 1996, Mitsubishi sold 32,405 units in Europe. From January through July of 1997, that number rose to 33,284 units, a 23 percent increase over the same period in 1996. This growth attests to the smooth development of Mitsubishi’s strategic European model.
Plans aim for 90,000 units to be sold in Europe each year when the GDI engine is installed, with more than half of these being GDI-powered vehicles.
Three GDI engines have been created by the firm to date: the 1.8-liter engine found in the GALANT/LEGNUM and CARISMA, the 3.0-liter engine found in the DIAMANTE, and the 3.5-liter engine found in the PAJERO and CHALLENGER. The firm will employ GDI engines to power two more models this year and expects to increase the number of models using the engine next year. The company is presently moving forward with development targeted at adapting GDI technology to various sizes of engines.
According to these plans, the business intends to gradually boost the Kyoto Plant’s GDI engine production capacity. Before the end of the year, production will expand from the current rate of 20,000 units per month to 30,000 units, and then to 40,000 units in the second half of 1998.
Prior to the GDI CARISMA’s introduction in Europe, the business ran an economic test for ten days, from August 9 to August 18. Driving the 6,400 kilometers from Jyvaskyla, Finland, to the Cape of Roca, Portugal, required three ADAC officials to alternate shifts behind the wheel. The GDI CARISMA completed the run with a fuel usage of 311 liters, or 4.83 liters per 100 kilometers. The 1.8-liter SOHC CARISMA, which also participated in the race, used 383 liters, with a 5.90 liters/100 km average fuel usage.

Utilizes Mitsubishi GDI?
The business applied gasoline direct injection technology*4 in a production model for the first time in August 1996. Eleven Mitsubishi Motors models currently use GDI engines, and by the year 2010, the firm hopes to use this technology in all of its models.
What vehicles have GDI engines?
Although they were aware of GDI at the time, American manufacturers didn’t actively explore it until a few years later. This might have been because delivering fuel-efficient engines like GDIs wasn’t as urgently needed in the late 1990s and early 2000s when oil and gasoline made from it were more affordable.
That has radically changed now that Ford and GM are promoting the technological advancements contained in their GDI designs. With more than a dozen models set to receive Ecotec powertrains by the 2010 model year, GM’s Ecotec direct injection engine family will become an increasingly important part of its car and SUV lineup.
Additionally, Ford declared that between 2009 and 2013, more than 2.5 million vehicles would be equipped with its “EcoBoost” gasoline direct injection engine. The company intends to install them in its Ford Flex crossover, Taurus, and Lincoln MKS, and claims that users may experience up to a 20% improvement in fuel efficiency. Audi, BMW, Hyundai, Kia, Mazda, Mercedes-Benz, Nissan, Lexus, Saab, Subaru, and Volkswagen are some of the other automakers that currently sell or plan to sell GDI engines.
The key question is whether more cutting-edge technology will surpass gasoline direct injection. The general public’s interest has also been piqued by hybrid gasoline and electric engines. Eventually, plug-in systems that let drivers to recharge car batteries from a house outlet may also catch on. Furthermore, the Honda FCX suggests that fuel cell-powered hydrogen vehicles may not be as far off as previously believed.
But most likely, direct injection will act as a transitional step to those more exotic choices, according to automotive analysts. Therefore, if you can’t wait for the quiet, clean “car of the future” but still want to save some money at the pump, a vehicle with direct injection might be the way to go. See the links below for more details on engine technology.
The gasoline direct injection (GDI) engine that Mitsubishi is introducing is described in this article.
There are three unique air-fuel mixture operating modes for the engine.
The air-fuel ratio can surpass 100 when operating at idle and partial load, making fully unthrottled operation possible.
In order to introduce significant exhaust gas recirculation, the engine is throttled slightly and the air-fuel ratio is adjusted between 30 and 40. To achieve the best fuel economy for medium loads, the ratio is regulated between 20 and 25. To lower exhaust temperatures and safeguard the three-way catalyst when operating at greater loads, the mixture is either stoichiometric or very slightly rich. The engine combines a complex electromagnetic swirl injector, “reverse tumble” in-cylinder flow, and a spherical compact piston chamber to produce the necessary combustion characteristics. To ensure even driving, the fuel injection modes must frequently be changed and the torque must be maintained at a steady level. The new GDI engine provides about 7% greater fuel economy than a diesel engine of equal size, 85% more power, 13% more maximum torque, 10dB less noise levels at all speeds, 8% less weight, and 40% less production costs.

Are all new automobiles GDI?
Nearly half of all new automobiles sold in the US now have (GDI) Gasoline Direct Injection engines. This is applicable to all sales vehicles, light trucks, station wagons, and SUVs.
On the majority of high-end and luxury vehicles on the market today, direct injection is an option. The method lowers fuel consumption while increasing a vehicle’s horsepower.
In essence, GDI is a fuel injection technology that injects gasoline directly into the combustion chambers under pressure. The direct transport of fuel improves a vehicle’s fuel efficiency.
Large automakers have their own phrase they use to describe the technology. Ford has given it the name EcoBoost, while Mercedes has called it CGI.
The technology that can regulate the flow of fuel right into the chambers is not limited to GDI. Gasoline Port Fuel Injection and Dual Port Injection are GDI substitutes.
The fact that the air-fuel mixture is evenly distributed prior to injection into the cylinders is one of the biggest benefits of a (PFI) Port Fuel Injection system. As a result, any gasoline residue produces less carbon buildup.
Which is preferable, GDI or MPi?
The output and torque of the GDI engine are about 10% higher at all speeds compared to conventional MPI engines of a similar size. The GDI engine delivers great acceleration while operating in high-output mode.
What is Mitsubishi Mivec?
Mitsubishi Innovative Valve Timing Electronic Control system “MIVEC” Variable Valve Timing Mechanism A variable valve timing system called the new MIVEC reduces fuel consumption. To lower intake resistance, the intake valve lift is continuously adjusted based on the operating circumstances.
Which automobiles feature port and direct injections?
For “advanced dual port and direct injection, also known as dual fuel delivery,” Ford and other OEMs have coupled PFI with GDI. Redesigned Ford V6 and 3.5L EcoBoost engines are two examples. 2GR-FSE Lexus engines.
What is the lifespan of a GDI engine?
A Gasoline Direct Injection (GDI) engine has many advantages over traditional engine systems. You obtain substantially better fuel efficiency with GDI systems, increasing your gas mileage. The fuel burns evenly and fully throughout the system, ensuring better fuel economy.
The technology known as Gasoline Direct Injection makes it feasible to get more power out of smaller car engines. You may easily pass emission tests and make your car environmentally friendly by taking advantage of low gas emissions.
Q: What does GDI mean Kia?
One of the best gasoline direct injection (GDI) engines in the auto business is the KIA GDI. The performance and fuel efficiency of Kia automobiles are greatly improved by these engines. The Kia GDI engines are built for strength and quick acceleration while also being very fuel-efficient. Even in challenging driving circumstances, GDI engines let drivers experience a peaceful, enjoyable, and pleasant ride.
Q: Is GDI a diesel?
No, GDI engines use gasoline instead of diesel (petrol). Petrol Direct Injection is another name for gasoline Direct Injection engines (PDI). This system delivers gasoline to the combustion chamber of internal combustion engines that run on gasoline (gasoline). The manifold fuel injection system, which injects fuel into an intake manifold, is not the same mechanism.
However, GDI engines are relatively similar to DI (Diesel Injection) engines, but they use gasoline and a strategically placed spark plug in place of an in-cylinder injection system and an automatic ignition system for the diesel fuel. Diesel is not used in gasoline direct injection engines; only gasoline is used.
Q: How long will a GDI engine last?
Engines with gasoline direct injection have shown to be more robust than those without. GDI engines have a fairly long lifespan and only need maintenance when they have traveled between 20,000 and 40,000 kilometers. But you must be sure to repair your GDI engine on a regular basis. Use only recommended or premium oil while changing the engine oil, as directed by the manufacturer. When the time comes, replace the spark plugs, and use high-quality, detergent-rich fuel. Additionally, you can use fuel system cleansers to maintain your GDI engine running at its best.
Q: Is GDI a turbo?
One of the newest technologies created to solve engine issues, notably with fuel efficiency, is TGDI (Turbocharged Gasoline Direct Injection) engines. This approach is being used by numerous automakers in multiple nations, including those in China, Mexico, and the United States of America. Automobile manufacturers have benefited greatly from the use of TGDI systems in order to achieve strict fuel efficiency standards.
Are GDI engines reliable?
Automakers have hailed gasoline direct injection (GDI) as a major accomplishment. The biggest names in the industry praise its improved performance and fuel economy as the most recent fuel delivery technology.
Also, it’s not simply hype from the industry. GDI engines have generated some remarkable outcomes.
In the Mazda 3, GDI has achieved success. The new Skyactiv engine’s gas mileage increased from 28 mpg to 32 mpg when Consumer Reports tested it. Cadillac was able to increase the CTS’s horsepower by 34 without reducing its fuel efficiency.
More cars than ever use gasoline direct injection, which has snuck into the mainstream. Automakers are confident that GDI is effective and reliable.
What is Gasoline Direct Injection and how does it work?
Fuel is injected into the combustion chamber of gasoline direct injection engines at high pressure. Compared to earlier fuel injection systems or carburetors, this is much more accurate.
Because of the direct injection, the combustion is more thorough and the cylinder temperature is kept lower. With a superior compression ratio made possible by the colder temperatures, more power and efficiency can be produced with the same quantity of gasoline.
Some manufacturers claim that GDI engines may increase low-end torque by 50% while still delivering a 15% boost in fuel efficiency.
Everything here could seem too nice to be true. In a sense, it is. Although GDI technology unquestionably leads to efficiency advantages, it also brings about a whole new set of issues.
GDI problems
Precision, the primary benefit of gasoline direct injection technology, is also its primary disadvantage.
The National Highway Traffic Safety Administration has received several complaints from consumers who own GDI-powered vehicles about how frequently the fuel system becomes clogged and engine carbon builds up.
The effects can be severe; some drivers may experience power reduction and engine stoppage. These are not inexpensive fixes, as anyone who has needed engine work can attest.
How to solve GDI problems
A large number of the automakers that have used this technology have stepped up to try and solve it.
BMW and Kia have particularly instructed their dealerships to suggest ethanol-free gasoline brands and gasoline with detergents in technical service bulletins to its customers. Additionally, they have advised owners to occasionally add a fuel-system cleanser to their car.
Several engineering remedies have been tried by some other automakers. A modified engine that can spray a little amount of fuel onto the valves themselves to serve as a solvent and keep them clean is one example.
However, doing regular maintenance is the best way to keep your GDI engine working smoothly and efficiently.

Direct injection or port injection: which is preferable?
A more sophisticated variation of multiport systems is gasoline direct injection (GDI), in which fuel is injected directly into the combustion chamber rather than through the intake port. Direct injection boosts fuel economy, reduces pollutants, and improves combustion efficiency.
Although both systems use electronic fuel injectors to dispense fuel into the engine, there is a distinction in the location of the fuel’s discharge. In port injection systems, the intake ports are sprayed with fuel.
Throttle body injection, port fuel injection, sequential fuel injection, and direct injection are the four fundamental types of fuel-injection systems now in use. The main advantages of direct-injection technology are somewhat higher power and better fuel economy for most applications.
