The ESA (Electronic Spark Advance) system is a system that uses the engine ECU to determine the ignition timing based on the signals from the various sensors. The engine ECU calculates the ignition timing Read more ESA (Electronic Spark Advance) system
4. Acceleration enrichment
The air-fuel ratio becomes lean, especially during the start of acceleration because a fuel supply lag tends to occur during acceleration against the rapid change of the amount Read more Various Corrections in Gasoline Engine Injection Control System 2 of 2
1. Start enrichment
The basic injection duration cannot be calculated from the amount of the intake air because the engine speed is low and the changes in the amount of the intake air are large at starting. Read more Various Corrections in Gasoline Engine Injection Control System 1 of 2
The engine ECU changes the fuel injection volume by changing the injector injection duration. The actual fuel injection duration is determined by the following two items.
1. The basic injection duration Read more Gasoline Engine Fuel Injection Duration Control
1. Fuel filter
The fuel filter removes dirt and impurities from the fuel that is compressed by the fuel pump.
2. Fuel pump filter
The fuel pump filter removes dirt and impurities from the fuel before Read more Gasoline Engine Fuel Filter/Fuel Pump Filter
The fuel is taken from the fuel tank by the fuel pump and sprayed under pressure by an injector. The fuel pressure in the fuel line must be regulated to maintain stable fuel injection by the pressure regulator Read more Gasoline Engine Fuel System/ Fuel Pump and Pressure regulator
The EFI system uses various sensors to detect the engine condition and vehicle running condition. And the engine ECU calculates at the optimum fuel injection volume, and causes the injectors to inject Read more Gasoline Engine EFI (Electronic Fuel Injection) Fuel System
1.Precautions on handling
(1) The engine oil used for the engine equipped with the turbocharger is used for not only lubricating the engine but for lubricating and cooling the turbocharger. As the engine Read more Precautions for Turbocharger
The water-cooled type intercooler utilizes coolant to cool the intake air. Although it utilizes coolant, the intercooler has its independent cooling system, not introducing the coolant from the engine Read more Water-cooled Type Intercooler
