Buffer decompression starting device and novel single cylinder diesel formed by same

Abstract

The invention discloses a buffer decompression starting device comprising an air inlet pipe body provided with connecting heads at two ends, a center shaft radially penetrating the air inlet pipe body, a choke plate located in the air inlet pipe body, matched with an inner cavity of the air inlet pipe body and fixedly connected with the center shaft, at least one air inlet hole formed in the choke plate, and a rotating handle arranged outside the air inlet pipe body and used for controlling the center shaft to rotate. The invention further discloses a novel single cylinder diesel formed by the buffer decompression starting device. The rotating handle is operated to rotate the center shaft, the choke plate is limited and adjusted at two special positions through a locating mechanism, the starting air input of the single cylinder diesel is controlled and an accelerator is adjusted by means of the relative positions of the choke plate and the air inlet pipe body and the ventilation function of the air inlet hole, therefore, the starting recoil force is reduced and the operation cycle of a piston is shortened to reduce the starting force on the condition of not breaking the original necessary starting conditions of the single cylinder diesel.

Description

technical field [0001] The invention relates to the field of single-cylinder diesel engines, in particular to a buffer decompression starting device and a novel single-cylinder diesel engine composed of the same. Background technique [0002] In recent years, with the country's strong support for agricultural development and the vigorous investment of agricultural machinery purchase subsidy funds, my country's agricultural mechanization has been vigorously developed. Diesel micro tillage machines, diesel water pumps, and diesel generators are also widely used in rural areas. These The power equipment usually used in agricultural machinery is a single-cylinder diesel engine, and the single-cylinder diesel engine is generally started by hand or hand. But now a large number of young laborers in rural areas go out, and those who stay at home are the elderly and women, who have less strength. During use, the diesel engine requires a greater force to start, which makes it difficul...

Problems solved by technology

But now a large number of young laborers in rural areas go out, and those who stay at home are the elderly and women, who have less strength. During use, the diesel engine requires a greater force to start, which makes it difficult to start and seriously affects the diesel engine. the widespread use and popularity of

[0003] Although some existing diesel engines are equipped with certain auxiliary starting devices when they leave the factory, such as electric starting devices or spring preloaded cranking starting devices, these auxiliary starting devices can alleviate the difficulty of starting to a certain extent, but these auxiliary devices The cost is high, the service life is short, and the operation is more troublesome

For example, the cost of a set of electric starting device is about 600 yuan, and the general service life is two years; a set of spring preloaded swing starter is about 500 yuan, but there are too many faults
