Vertical type single-cylinder diesel engine

Abstract

It relates to a vertical mono cylinder diesel that comprises the crankcase with bottom being able to contain lubricants, air cylinder cap assembly matching with the crankcase, air cylinder assembly, fuel structure matching with the air cylinder assembly, drive structure inside the crankcase, cooling device hang outside with distribution cam set and arm rotating set, the distribution cam set fixed inside the gear chamber of the crankcase, rocking arm set supported on the rocking arm base and fixed on the air cylinder cap assembly, with the drive mechanism composed of serial connected start generator, flywheel gear and crank inside the crankcase, drive arm connecting with the piston inside the ari cylinder assembly, one end of the crank having timing gear, rocking arm shaft of the distribution mechanism having oil inlet and outlet connecting with the inner cavity of the rocking arm shaft, lubricant oil supply mechanism having oil inlet and outlet on the crankcase. It has fixed rotation speed, good in lubrication effect, fine in cooling feature, and light in size.

Description

technical field [0001] The invention relates to a vertical single-cylinder diesel engine. Background technique [0002] At present, the single-cylinder diesel engines on the market, especially the vertical single-cylinder diesel engines, mostly adopt the form of oil mist splash lubrication. Cooperating with the centrifugal movement of the high-speed moving parts to form oil mist, which enters the rocker chamber of the cylinder head assembly to lubricate the components in the rocker chamber. But in the actual use process, when the working speed of the diesel engine is high, the oil quantity and oil film required on the surface of each friction pair cannot be controlled in a balanced and stable manner, the lubrication effect is not good, and the oil mist lubrication method cannot meet the high speed requirements of the diesel engine , to a certain extent, restricts the development of diesel engines in the direction of high speed. At the same time, most of the existing vertic...

Problems solved by technology

But in the actual use process, when the working speed of the diesel engine is high, the oil quantity and oil film required on the surface of each friction pair cannot be controlled in a balanced and stable manner, the lubrication effect is not good, and the oil mist lubrication method cannot meet the high speed requirements of the diesel engine , to a certain extent restricts the development of diesel engines in the direction of high speed

At the same time, most of the existing vertical single-cylinder diesel engines use a cooling mechanism composed of a flywheel fan and a radiator with a wind guide. After the cooling air enters the radiator, it needs to change its direction. There are many corners in the flow direction and the resistance of the cooling air flow is large, resulting in a low utilization rate of the cooling air, which cannot meet the heat load requirements after the design speed of the diesel engine is greatly increased.
