Single-cylinder four-stroke gaseous propellant engine

Abstract

The invention relates to a motor, in particular to a single cylinder four-stroke motor using gas fuel. The motor is provided with a body that is provided with a cylinder head and a piston, the cylinder head is provided with a spark plug and an inlet channel, and the piston is under the inlet channel; a combustion chamber is arranged between the bottom surface of the cylinder head of the body and the top surface of the piston of the body, under the spark plug and the inlet channel and is linked with an ignition device which is respectively communicated with the inlet channel and an exhaust device. The single cylinder four-stroke motor improves the power of the generator, saves energy ( less gas consumption), has low emission and cost and is safe and reliable by improving the ignition device and the combustion chamber, etc.

Description

technical field [0001] The invention relates to an engine, in particular to a single-cylinder four-stroke engine using gaseous fuel. Background technique [0002] Gas fuel engines generally use gasoline engines or diesel engines as original engines, modified and optimized engines. Due to the characteristics of single-cylinder engine structures and uses, some advanced technologies on vehicle engines cannot be used due to factors such as structure or cost. At present, the power of gas engines using mechanical intake mixers is 10-20% lower than that of gasoline engines or diesel engines, and the harmful exhaust emissions are also higher, and the emissions cannot meet the emission regulations of relevant countries; external purification generally uses catalysis Measures such as converters are relatively expensive, and will cause local overheating on the surface of the engine muffler to pose a safety hazard.

Problems solved by technology

[0002] Gas fuel engines generally use gasoline engines or diesel engines as original engines, modified and optimized engines. Due to the characteristics of single-cylinder engine structures and uses, some advanced technologies on vehicle engines cannot be used due to factors such as structure or cost. At present, the power of gas engines using mechanical intake mixers is 10-20% lower than that of gasoline engines or diesel engines, and the harmful exhaust emissions are also higher, and the emissions cannot meet the emission regulations of relevant countries; external purification generally uses catalysis Measures such as converters, but the relative cost is relatively high, and it will cause local overheating of the surface of the engine muffler, which will pose a safety hazard

[0003] Single-cylinder gas fuel engines use spark ignition for combustion, and currently there is no automatic adjustment device for ignition advance angle. In order to ensure normal operation at low speeds and heavy loads, the ignition advance angle is set to be small, resulting in combustion lag under the engine's calibrated operating conditions, high exhaust temperature, and high power. Small, the power of the gas engine is lower than that of the gasoline engine or the original engine of the diesel engine, and the combustion is not timely and perfect, and the engine emission is poor
