CN201078278Y - 1.3 L gasoline engine cylinder cap - Google Patents

Abstract

The utility model relates to a cylinder cap of a 1.3L gasoline engine of a straight four-cylinder, a four-valve, a direct injection, a spiral air inlet duct and an integral structure. A cylinder cap blank is moulded of thin walls and the minimum wall thickness is 4.5mm. Because the four-valve structure is adopted, the EU IV standard for swirl ratio adjustment can be met, so that the complexity of a valve mechanism structure can be reduced effectively and the cost is reduced. The height of the cylinder cover is 113mm, the distance between center connecting lines of an air inlet valve and an air exhaust valve and a center line of the cylinder is 1.95mm and the distance between the center connecting lines of the air inlet valve and the air exhaust valve and a firepower face is 47.1mm. The included angle between the air inlet valve and the air exhaust valve is 34 degrees. Mounting holes of a fuel injector is arranged on the cylinder cap and the included angle between a mounting angle and the firepower face 46.5 degrees. The utility model can meet the requirement of EU IV standard for the discharge of the 1.3L engine.

Description

1.3L petrol engine cylinder cap

Technical field

The utility model relates to technical field of internal combustion engines, relates in particular to the petrol engine cylinder cap.

Background technique

The effect of 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

The purpose of this utility model provide a kind of satisfy petrol engine Europe IV emission request, with the 1.3L petrol engine cylinder cap of 1.3L-1.5L petrol engine coupling.

Concrete structural design scheme is as follows:

1.3L the petrol engine cylinder cap comprises in-line four cylinder, four valves, straight spray, spiral inlet duct, monolithic construction cylinder cap;

Described cylinder head 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 °, 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.

The mechanical tappet of installation hole is arranged on the described cylinder cap.

Described cylinder cap is provided with the oil circuit that pressure regulator valve (OCV) control phase regulator 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 °.The utility model can satisfy the needs of 1.3L Europe IV discharging Engine Matching.
