The YC6G series engine is used in buses. It is developed based on the FEV technology platform, which has the following features and benefits. Firstly, Honeywell turbochargers equipped with bypass valves can provide quick response and higher performance. Secondly, there are cross-hatched grooves on the surface of the cylinder liner to reduce the total fuel consumption. Finally, the cylinder head gaskets are formed with metal plates, so it is highly durable and able to withstand high explosive pressures while reducing deformation around the cylinder bore.
