Abstract
The utility model discloses a cylinder cap for an engine of a car, which comprises a cylinder cap body 1, a cam shaft hole 2 and an intake duct opening 3, wherein the intake duct opening 3 is in a double-cavity type; the upper part of the cylinder cap body 1 is provided with a valve tappet hole 4 of an air distribution mechanism of the engine and an oil nozzle hole 5 of an intake manifold. The oil nozzle hole 5 is arranged above the intake duct opening 3. The cylinder cap solves the problem that when fuel oil is sprayed, the time for thoroughly mixing the fuel oil and the air in the intake duct is long. Thus, the engine can operate at high speed or at low speed; the output power is large, and the torsional moment is high. Therefore, the oil consumption is reduced; the exhaust can reach the standard of ohm II or ohm III to fit the requirements of energy saving and environmental protection of modern cars completely.
Description
One, technical field
The utility model relates to the cylinder head that a kind of motor car engine is used.
Two, background technique
Along with the appearance of environmental protection policy, automobile enters family comprehensively, and the motor that requires high-performance, low emission is the problem that Domestic Automotive Industry at first solves.Existing cylinder cover of automobile engine generally all drives camshaft work by valve rocker, its air inlet road junction is single formula, shape is fairly simple, and the oil nozzle design is on intake manifold, the well-mixed time of air when causing oil spout in fuel oil and the intake duct is longer, has influenced the overall performance of motor.When high engine speeds running or power per liter, its intake efficiency is relatively poor, causes engine output to descend, and is short of power; When time of engine low speed or small-power, because gas inertia increases, Engine torque is reduced, thereby cause the automobile fuel consumption to increase, discharging exceeds standard.
Three, model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and provide a kind of and make in the shortest time that oil gas fully mixes, motor output is high-power, the cylinder cover of automobile engine of high moment of torsion.
The purpose of this utility model realizes by following technical solution: a kind of cylinder cover of automobile engine, comprise cylinder head body, camshaft hole, air inlet road junction, described air inlet road junction is a bicavate, the cylinder head upper part of body is equipped with the valve tappet hole of the distribution device of this motor, the oil nozzle of intake manifold, and described oil nozzle is on the air inlet road junction.
After adopting the utility model structure, when motor car engine in when operation, fresh air directly fully mixes with the fuel oil that is positioned at cylinder upper part of the cover oil nozzle spirt by the bicavate intake duct within a short period of time, enters head combustion chamber by intake valve again, carries out work by combustion after the compression; Directly drive camshaft by the valve tappet in the valve tappet hole then, drive bent axle by the camshaft timing gear belt again and carry out energy transfer, can make motor no matter at a high speed or low-speed running, its output power is big, moment of torsion is high, thereby reduction oil consumption, discharging reaches Europe II or EUROIII Emission Standard, meets the requirement of Hyundai Motor energy-saving and environmental protection fully.
Four, description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model cylinder cover of automobile engine.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the plan view of Fig. 2.
Five, embodiment
With reference to Fig. 1, Fig. 2, Fig. 3 as can be known, the utility model cylinder cover of automobile engine, comprise cylinder head body 1, camshaft hole 2, air inlet road junction 3, described air inlet road junction 3 is a bicavate, the valve tappet hole 4 of the distribution device of this motor, the oil nozzle 5 of intake manifold are equipped with in the top of cylinder head body 1, and described oil nozzle 5 is on air inlet road junction 3.Wherein the valve tappet hole is used to install valve tappet, and camshaft hole can be designed to two, is used to install twin cam shaft, and the shape at the air inlet road junction of bicavate is optimized design.
Motor car engine is in running, fresh air can directly enter intake duct by the air inlet road junction after the bicavate optimization fully to be mixed with the fuel oil of superposed oil nozzle spirt within a short period of time, enter head combustion chamber by intake valve again, carry out work by combustion after the compression; Directly drive camshaft on the camshaft hole by the valve tappet in the valve tappet hole then, drive bent axle by the camshaft timing gear belt again and carry out energy transfer, make motor no matter at a high speed or low-speed running, its injection time is short, intake efficiency is high, reduced intermediate transport mechanism, improved efficiency of energy delivery, thereby engine output is big, moment of torsion is high, thereby under equal conditions reduce oil consumption, discharging reaches Europe II or EUROIII Emission Standard, meets the requirement of Hyundai Motor energy-saving and environmental protection fully.
