Japanese manufacturers are outdoing each other in the presentation of gasoline engines with direct fuel injection. After Mitsubishi and Toyota, it was Subaru's turn.
Mitsubishi is undoubtedly the leader in this competition, the GDI unit is installed in standard Galants. Subaru has presented a study of a powerful station wagon with four-wheel drive under the name a-Exiga, powered by a new four-cylinder boxer with direct fuel injection. The engine is connected to a continuously variable automatic transmission.
The Studio Subaru is a luxury six-seater limousine, in which passengers travel in three rows. The car is a carrier of future-oriented technical solutions. These include the multi-link rear axle, all suspension components are located under the floor of the vehicle. This design creates optimal conditions for third-row passengers. VDC driving dynamics control system (Vehicle Dynamie Control) increases active safety, a system ADA (Active Drive Assist), which consists of two cameras transmitting to the computer information about the current state of the road, it acoustically warns the driver of the impending danger.
If the vehicle driver does not react in time, The ADA enters the action by itself and slows down or avoids the obstacle.
Solution, which has a good chance of being used in the near future, is mounted in the Subaru 2.5-liter boxer studio. The Exigi engine delivers power 150 MILES. Due to direct fuel injection into the cylinder - the same principle as in diesel – petrol injection can be very precisely controlled, and the engine achieves high efficiency even in lean combustion. Contrary to conventional gasoline engines with catalytic converters and lambda probe, which consume the mixture in a stoichiometric ratio 1:14,7, the direct injection unit can run on a mixture of fuel and air even 1:40. As the manufacturer assures, its engine achieves a power higher by 10 proc., correspondingly higher torque, The 20 proc. lower fuel consumption and up to 90 proc. lower nitrogen oxide emissions compared to conventional gasoline units.
