Both the swirl chamber combustion chamber and the pre-chamber combustion chamber use pin injectors, which have low fuel injection pressure and work reliably; because the swirl in the swirl chamber increases with the increase in speed, the diesel and air can still be well maintained at high speeds. mix.
The rotational speed of the swirl chamber diesel engine can reach more than 4000 rpm, the working process is soft, and the harmful components in the exhaust gas are less. However, the heat dissipation loss and gas flow loss are large, and the afterburning is more serious, so the fuel consumption rate is high; cold car start is difficult, and it is often necessary to install a glow plug.
