Abstract

The invention relates to a small single-cylinder water-cooled type diesel engine. The small single-cylinder water-cooled type diesel engine comprises a engine body, a cylinder liner, a cylinder coverand an external water-cooled circulating channel; a water-cooled sleeve is arranged on the periphery of the cylinder liner, a cooling channel is distributed on the cylinder liner, an outlet end of thewater-cooled sleeve is connected with an inlet end of the cooling channel, and a thermostat is arranged at an outlet end of the cooling channel; and the water-cooled circulating channel comprises a small cycle and a large cycle. The invention aims to provide the small single-cylinder water-cooled type diesel engine capable of automatically adjusting a cooling mode. The small single-cylinder water-cooled type diesel engine has the advantages that the thermostat is arranged at the outlet end of the cooling channel, the water-cooled circulating channel is provided with the small cycle and the large cycle, the thermostat can automatically distribute cooling water into the small cycle or the large cycle according to the water temperature, and the circumstances that heat for applying work is taken away due to over-low temperature of the cooling water, and the fuel efficiency is reduced, or heat dissipation of the diesel engine is poor due to over-high temperature of the cooling water are avoided.

Description

Technical field [0001] The invention relates to a diesel engine, in particular to a small single-cylinder water-cooled diesel engine. Background technique [0002] Diesel engine working temperature is too high or too low will reduce its power and economy. The role of the cooling system is to keep the diesel engine working at the most suitable temperature to obtain good economy, power and durability. The existing cooling system can be divided into air cooling and water cooling according to different cooling media. Air-cooled diesel engine has simple structure and small volume. Compared with water-cooled diesel engine, it reduces parts and components, simplifies the structure, simplifies the production process, and reduces production cost; water-cooled diesel engine has uniform cooling, good cooling effect, and generates noise It is much smaller than the air-cooled diesel engine. [0003] When the diesel engine works in an environment with high temperature or poor ventilation, the...
