Abstract

Disclosed is an automobile engine driven by methanol. The automobile engine comprises a cylinder cover, a cylinder body, a curve shaft, pistons, a connecting rod, a cylindrical tube, an air inlet valve, an air outlet valve, a valve lifter, an atomizer, an air inlet pipe and an air outlet pipe, wherein the atomizer and the air inlet pipe are connected, the air inlet pipe and a burning chamber are in communication, the air inlet pipe pierces the air outlet pipe, the air outlet pipe is communicated with the air outlet of the engine via the connecting pipe and a siphon. Gas in the air inlet pipe atomized by methanol is heated by the discharged heat resulting from the process of the engine, and thereby the atomization degree of the methanol is increased. The utility model is simple in structure, low in costs and obvious in effect.

Description

Overhead type methanol vehicle motor

Affiliated technical field

The utility model relates to a kind of waste heat that utilizes motor to be in operation, and the methyl alcohol atomization gas of low temperature is heated, thereby improve the overhead type methanol vehicle motor of methyl alcohol mixed gas fogging degree.

Background technique

At present, known motor car engine exists the burnup height based on combustion gasoline or diesel oil, and exhaust emissions is to problems such as pollution of atmosphere are serious.

Consult shown in Figure 1: orthodox car motor inlet and outlet manifold configuration and working principle: the fuel gas of atomizing is by the atomizer generation power that burns through the firing chamber that air intake branch enters motor, waste gas after burning is discharged by exhaust branch pipe, and air intake branch and exhaust branch pipe are respectively two independent structures.

Summary of the invention

For overcome existing motor car engine can not burning methanol and burning methanol after atomizing bad, the clean problem of burning.The utility model provides a kind of overhead type methanol vehicle motor, and the waste heat that utilizes engine operation to discharge is heated to the methyl alcohol atomization gas, thereby improves the fogging degree of methanol fuel.

The technological scheme that its technical problem that solves the utility model adopts is: atomizer is communicated with suction tude, suction tude is communicated with engine chamber, suction tude is passed from outlet pipe, outlet pipe is communicated with exhaust opening of engine through connecting tube, bend pipe, utilizes the waste heat of motor combustion gas that the methyl alcohol atomization gas is heated.

The beneficial effects of the utility model are:

1, improved the fogging degree of methanol fuel;

2, reduced environmental pollution, because methyl alcohol fogging degree height, burning is clean, and the burning back is minimum to the pollution level of air;

3, simple in structure, cost is low, and fault is few, and is easy to maintenance.
