  • Patent number: 11285797
    Abstract: A side part structure of an engine having cylinders lined up in a front-and-rear direction of a vehicle body, is provided. The structure includes auxiliary machinery disposed in a front part of one side wall part of the engine in a vehicle width direction, a fuel system component disposed in a rear part of the side wall part, an intercooler disposed between the auxiliary machinery and the fuel system component, and a first protector member disposed between the intercooler and the fuel system component. At least a front part of the first protector member is formed so as to be separated from the side wall part as it extends rearward. A front part of the intercooler is disposed rearward of the auxiliary machinery and the intercooler is disposed along the first protector member so as to be separated from the side wall part as it extends rearward.

  • Patent number: 10895215
    Abstract: A control system for a pre-mixture compression-ignition engine is provided, configured such that in a first combustion mode, the control unit controls the fuel injection valve to have a fuel amount within a mixture gas in an outer circumferential portion of the combustion chamber larger than in the center portion, the swirl generating part to generate a swirl flow in the outer circumferential portion, and the spark plug to ignite the mixture gas in the center portion. In a second combustion mode, the control unit controls the fuel injection valve to start a fuel injection on intake stroke so that the mixture gas is formed in the entire combustion chamber, the swirl generating part so that a swirl flow becomes weaker than in the first combustion mode, and the spark plug to ignite the mixture gas before CTDC.
