Embodiment Construction

[0026] 1: The opening and closing of the intake and exhaust valves 4; 5 is controlled by the timing cam 8; 9 of the valve train, and the method of controlling the intake and exhaust valves 4; 5 of the two cylinders at the same time is to make the timing cam 8; 9 of the two cylinders The gas distribution phase design is consistent.

[0027] 2: At present, the oil pumps that control the fuel supply are divided into two types: mechanical and electric injection. The picture shows the mechanical oil pump. The mechanical pump uses the oil pump cam 7 to compress the oil cylinder plunger to increase the oil pressure and spray fuel. The phase angle of the oil pump cam 7 rotation is what controls the oil pressure rise to form the fuel injection timing. Therefore, in order to realize the synchronous timing fuel injection of the two cylinders, the phase angles of the oil pump cams 7 of the two cylinders must be consistent.

[0028] The fuel injection timing of the EFI fuel pump is contro...

Abstract

The invention provides a novel work application mode for an internal combustion engine. In each work application stroke, two-cylinder or multi-cylinder pistons are combined for implementing the synchronous work application. The technology is mainly used for the internal combustion engine model with more than four cylinders, and aims at achieving the goal of enabling a crank shaft to form the greater torque via the reasonable centralized utilization of piston driving force so that stronger output motive power is generated. A novel work application mode has the effects that the crank shafts in the same models generate twice torque and rotating acceleration, and the motive power of the engine can be improved by about 50 percent except the adverse factors such as work application time reduction and work application interval delay. The novel work application mode also has the beneficial effects that the conflict between the torque and the rotating speed is neutralized, so the large-torque engine realizes high speed, and large-size engines with super power can be designed; in environment-protection and energy-saving aspects, after the motive power demand is surplus, the fuel can be reduced through lowering the power, and the fuel saving effect is bout 30 percent.

Description

technical field [0001] The invention relates to an internal combustion engine, which relates to a high-torque high-speed internal combustion engine formed by adopting a new working method. Specifically, it is on a multi-cylinder internal combustion engine; the cylinder pistons of two or more cylinders are synthesized to perform synchronous work, and the effect is to synchronously strengthen the torque and speed of the internal combustion engine. This technology is applicable to all kinds of internal combustion engines with more than four cylinders, such as single-row and V-type, and can greatly increase the output power on the basis of the original structure. Background technique [0002] The internal combustion engine takes the crankshaft to rotate 720 degrees as a work cycle. In a cycle, all cylinders complete the four strokes of intake, pressure, power and exhaust in sequence. [0003] In the cycle of doing work sequentially, the more internal combustion engines with mo...
