The utility model can effectively lower the structural complexity of the gas-distribution system and lower the cost; the utility model can meet the matching requirement for 1.3L European IV emission engine.

Description

1.3 rise the petrol engine cylinder cap

Technical field

The utility model relates to a kind of petrol engine cylinder cap.

Background technique

The effect of gasoline engine cylinder head is the common bags that forms of blanket gas cylinder sleeve and piston, and mechanical stress of bearing and thermal stress are very big.Valve reasonable in design (number, size) and inlet and outlet road can guarantee high charging efficiency and lower manufacture cost.The size of the cylinder cap of this type of motor is little, combustion-chamber shape is simple, and low cost of manufacture can obtain different swirl rates and circulation coefficient by the part adjustment to intake duct under the prerequisite that does not change jacket structure for water, satisfy multiple power range Engine Matching needs, the product extensibility is strong.In order to solve cooling and rigidity problem, adopting the cooling water channel of boring is current major technique measure.

The model utility content

In order to satisfy petrol engine Europe IV emission request, to mate with the 1.3L-1.5L petrol engine, the utility model patent provides a kind of 1.3L petrol engine cylinder cap.

The design proposal that realizes above-mentioned purpose is such:

Comprise in-line four cylinder, four valves, tangential inlet duct, monolithic construction cylinder cap 1.3 rise the petrol engine cylinder cap;

Described cylinder cap height A is 113mm, intake valve, the exhaust valve line of centres are apart between the cylinder centerline being 1.95mm apart from B, intake valve, the exhaust valve line of centres are 47.1mm apart from the distance C of fire power face, angle α between intake valve, the exhaust valve is 34 °, the angle of inclination beta of mounting hole of oil sprayer and Vertical direction is 43.5 °, and the angle of inclination beta of mounting hole of oil sprayer and Vertical direction is 43.5 °;

Described intake valve throat diameter D is ￠ 26mm, and exhaust valve throat diameter E is ￠ 22mm.

Described cylinder cap is provided with the oil circuit that pressure regulator valve is installed.

Useful technique effect of the present utility model is, adopts four air valve structures, when satisfying the requiring of Europe IV discharging by the swirl rate adjustment, can effectively reduce the complex structure degree of distribution device, reduces cost.Cylinder cap is arranged mounting hole of oil sprayer, and setting angle and fire power face angle are 46.5 °, and the utility model can satisfy the needs of 1.3L Europe IV discharging Engine Matching.
