Description
Technical field
The present invention relates to motor, relate more specifically to alcohol and hydrogen mixed combustion engine unit.
Background technique
The use of Aalcohols fuel in internal-combustion engine had it long ago.The oil crisis of the seventies in 20th century is arisen at the historic moment methanol and alcohol powered automobile.It is extensive that it has raw material sources; Cost of production is relatively cheap; The easiest transformation forms the alcohols motor on now with the petrol and diesel oil machine, but also have that power does not reduce, the thermal efficiency can improve, by degradation advantage under the aggregate level of the oil consumption decline of calorific value, blowdown.
But, because the Aalcohols fuel latent heat of vaporization is big, be unfavorable for the burning of flame propagation mode, in motor, there are some flame-out districts more or less.In addition, the calorific value of Aalcohols fuel is starkly lower than petrol and diesel oil, if by the weight of fuel consumption calculating, its economic benefit is not obvious.Its three, though after using pure fuel, harmful gas CO, the HC of its motor, NO
xAll reduce significantly (reducing 30-45% approximately), but because of Aalcohols fuel under the engine low load operating mode, operating temperature is low, velocity of propagation of flame is slow, causes atypical harmful matter formaldehyde emissions to increase, big several times when it is worth comparable use petrol and diesel oil machine.
Because the required ignition energy of hydrogen low (have only 1.5 millis burnt) but, the wide lean-burn degree of knock limit greatly, easily realizes rare mixed burning, velocity of propagation of flame is faster, velocity of combustion is fast, burn that the constant volume degree is good, burning capacity is minimum later.But, since the gaseous density of hydrogen (dry air is 1.293kg/m
3, hydrogen is 0.0899kg/m
3) and the gaseous state relative density (air is 1, and hydrogen only is 0.0696) all be minimum in gaseous fuel, so volume calorific value of hydrogen mixed gas low (because hydrogen has accounted for about 1/3 volume), so under equal conditions, use the peak output of the motor of hydrogen fuel to have only about 60% of petrol engine merely.As obtaining same constant power, just must strengthen the volume of motor, brought new problem so again.So present pure combustion hydrogen engine practicability also has many difficulties to overcome.Therefore having the people to test uses hydrogen fuel to add the motor that Fuel Petroleum mixes.The shortcoming of this motor is to need two kinds of fuel tanks, and the volume of device is bigger, and the supply of different fuel is also very inconvenient.
Summary of the invention
The objective of the invention is to solve the shortcoming that the motor of prior art exists, a kind of Aalcohols fuel motor is provided,, change engine cylinder internal combustion characteristic, realize efficient low-consume, and can reduce emission of harmful substances such as formaldehyde by alcohol and hydrogen mixed.
For realizing above-mentioned purpose of the present invention, the invention provides a kind of alcohol and hydrogen mixed combustion engine unit, comprise a vehicular engine, a pure part of the fuel supply, an air is supplied with part, an ignition section, with a discharge portion, described pure part of the fuel supply comprises a pure fuel tank, Aalcohols fuel wherein is housed, the outlet of described pure fuel tank connects a pure mechanical pump by pipeline, connect a filter cleaner at the mechanical delivery side of pump of alcohol by pipeline, described filter cleaner is connected with described motor by pipeline and an atomizer, it is characterized in that described engine device also comprises a cracking hydrogen production part, described hydrogen cracking section comprises a cracking hydrogen production device, a gas tank, a gas solenoid valve and a hydrogen control valve, the upstream of described cracking hydrogen production device is connected with described pure fuel tank by pipeline, described cracking hydrogen production device is connected with described gas tank by pipeline, described gas tank is connected with described gas solenoid valve and described hydrogen control valve by pipeline, and described hydrogen control valve is connected with described motor by pipeline.
Alcohol-hydrogen mixed-combustion engine of the present invention can carry out the part and convert on existing motor.Alcohol-hydrogen mixed-combustion engine of the present invention is mixed hydrogen burning by making Aalcohols fuel, and engine operation stability is improved, and eliminates circulation and catches fire, and promotes the uniformity of burning.This motor is obtained the higher thermal efficiency, better economic and environmental-protecting performance under the various working conditions of motor, compare with petrol engine, its CO, HC, NOx will reduce more than 50%, compare with clean burn Aalcohols fuel motor, and its CO, HC, NOx also will reduce more than 20%.The application of alcohol and oxygen engine of the present invention can make Aalcohols fuel occupy bigger proportion in the energy.
