Description

The 4G18 Mitsubishi engine with a displacement of 1834cm3 adopts the technology of directly injecting gasoline into the cylinder GDI (gasoline direct injection), and directly injects gasoline into the cylinder to achieve high-response and high-precision fuel control.

The structure design is compact, and compared with the engine of the same displacement, the overall size is small and the weight is light. Adopt high-efficiency combustion methods such as rolling combustion and optimal fuel injection, and reduce engine noise to a minimum by strengthening the rigidity of the cylinder block and crankshaft and using shock-absorbing resin materials for some parts. With the advanced electronic fuel injection system, the emission can reach Euro 3 and Euro 4 standards, and the fuel consumption rate is low.

4G18 engine working principle:

Gasoline and air are injected into the cylinder through the intake hole and oil delivery hole, and are fully mixed in the cylinder. When the spark plug ignites the mixture, the mixture explodes and burns violently, pushing the piston down and generating power.

The huge pressure of the explosive gas also pushes open the air outlet of the one-way valve to discharge the exhaust gas. Then, the residual exhaust gas in the cylinder gradually becomes colder, the air pressure becomes lower, and the atmospheric pressure outside the cylinder pushes the piston upwards to prepare for the next explosion.

Compared with the hydraulic tappet type valve drive mechanism commonly used in gasoline engines, this novel valve drive mechanism has the advantage of relatively small friction torque, so the required driving force is also small, which can effectively reduce engine power consumption and fuel consumption.
