Description
Technical field
The present invention relates to a kind of prime mover, specifically a kind of piston direct-drive supercharged engine is design method both.
Background technique
As everyone knows, turbosupercharger is a kind of forced gas guidance system that is arranged on external engine.It compresses the air of inflow engine, and pressurized air can make motor more air can be pressed onto in the cylinder, and more air just mean can inject more fuel in cylinder.Therefore, the combustion stroke of each cylinder just can produce more power, and the power that turbosupercharged engine produces is more much bigger than the common engine of same displacement, so just can significantly improve the power weight ratio of motor.In order to obtain the lifting on this performance, the waste gas that turbosupercharger uses motor to discharge drives the turbine rotation, and turbine then drives the air pump rotation.The maximum speed of turbine in turbo machine is that per minute 150,000 changes---this is equivalent to 30 times of most of rotating speed of automobile engine.Owing to link to each other with outlet pipe, the temperature of turbine is very high usually simultaneously.Therefore, the fatal shortcoming of turbosupercharged engine is complex structure, cost height, working life is short, need periodic replacement, approximately be 100,000 kilometers working life, and every replacing once needs 20,000 yuan of RMB, because the waste gas that turbosupercharger uses motor to discharge drives the turbine rotation, the supply and exhaust road has increased resistance like this, produces certain influence for the power of motor.
Traditional piston engine mainly is made up of piston, connecting rod, bent axle, piston moves reciprocatingly in cylinder, drive bent axle by connecting rod and become the circumference rotation, in actual application, exist not enough the time, inefficiency is embodied in 1) connecting rod makes piston produce cross component force and the wearing and tearing of intensifying cylinder stress surface with the swing of bent axle easily, forms oval, the tightness that has reduced cylinder causes, and power reduces fuel consumption and increases; 2) inefficiency, piston makes a round trip in cylinder and drives one week of crankshaft rotating, in fact has only half acting, second half consumed power that is to say, during the combustion gas detonation, promote piston and move external acting, can only driven plunger rotate half cycle, and the angle of real acting is to spend between 135 degree 45 in this half cycle, the driving moment maximum of connecting rod between this angle.By above-mentioned analysis as can be seen, capacity usage ratio is low to divide exception except connecting rod swing overcomes the side direction of falling, and the acting angle of bent axle is little also to be main cause.
Summary of the invention
The reciprocal acting that the objective of the invention is to overcome the piston of existing reciprocating engine directly drives bent axle by connecting rod and becomes the deficiency that circumference rotates, and a kind of piston direct-drive supercharged engine is provided.
