Embodiment Construction

[0014] The technical solution will be further described in detail below through examples.

[0015] The fuel-saving device for a six-cylinder diesel automobile engine includes a common fuel injection pump 7 and six independent oil delivery pipelines connecting the fuel injection pump to the combustion chambers of each cylinder. 1 first cylinder, 2 second cylinder, 3 third cylinder, 4 fourth cylinder, 5 fifth cylinder, 6 sixth cylinder.

[0016] A first cylinder solenoid valve 11 is connected in series in the oil delivery pipeline from the fuel injection pump to the combustion chamber of the first cylinder 1, and the solenoid valve is controlled by a first cylinder solenoid valve switch 12 arranged in the cab. Similarly, a solenoid valve 61 of the sixth cylinder is connected in series in the oil delivery pipeline from the fuel injection pump to the combustion chamber of the sixth cylinder 6, and the solenoid valve is controlled by the solenoid valve switch 62 of the sixth cylind...

Abstract

An economizer for a 6-cylinder diesel engine for automobiles is provided, which pertains to the technical field of diesel engines for automobiles, essentially solves the economy in automobile running, and comprises a fuel injection pump and oil-delivery pipelines connecting the fuel injection pump with the combustion chambers of each cylinder. The economizer is characterized in that, in the oil-delivery pipeline from the fuel injection pump to the first and/or sixth combustion chamber, solenoid valves corresponding to the oil lines are connected in series; the control buttons of the solenoid valves are located at easily accessible positions for a driver. The economizer can select some or all cylinders to operate depending upon the load of the engine, saves fuel and improves operation effect while guaranteeing the steady operation of the engine, is especially suitable for freight diesel automobiles to run under mid and high speed.

Description

technical field [0001] The invention belongs to the technical field of diesel automobile engines, in particular to a fuel-saving device for a six-cylinder diesel automobile engine. Background technique [0002] The working process of a diesel engine is the same as that of a gasoline engine. Each working cycle also goes through four strokes of intake, compression, power, and exhaust. However, since the fuel used in the diesel engine is diesel oil, its viscosity is higher than that of gasoline, it is not easy to evaporate, and its auto-ignition temperature is lower than that of gasoline, so the formation and ignition of combustible mixtures are different from those of gasoline engines. [0003] Diesel engines inhale pure air during the intake stroke. When the compression stroke is close to the end, the diesel oil is raised to above 10MPa through the fuel injection pump, and the high-pressure fuel pump delivers the diesel oil to the fuel chamber of each cylinder, where it is m...
