A camshaft is a rotating object that contains pointed cams. These cams are what convert rotational motion into reciprocal motion. These devices are found in internal combustion engines, mechanically controlled ignition systems, and early electric motor speed controllers. Here's a look at some of their uses:::- During the combustion process, the rotating cams move from the engine's cylinders to a different position, which changes the flow of the fuel through the engine.A camshaft is a vital component of an engine. The shape of its lobes opens and closes the exhaust and intake valves in time with the piston's motion. The intake valve opens during the piston's intake stroke, closes when the piston bottoms out, and opens again during the exhaust stroke. The two lobes together control the airflow into and out of the engine. Once the cylinders are lubricated, the camshaft is responsible for the smooth running of the vehicle. The most common parts of a camshaft include the woodruff key, the lobe lift, and the cam's duration. These components are essential to the smooth running of the engine and are important to its performance. A poorly performing car will not run smoothly or be smooth when running. Hence, you should take your car to a mechanic immediately to avoid any mishap. A mechanic will be able to provide you with accurate information about your car's camshaft.

The engine Camshaft controls the timing of the intake and exhaust valves and is one of the most important components of the engine. This component determines the horsepower and RPM range of the engine and is also important for gas mileage and emissions. It can also affect the quality of idle and low-RPM drivability. In addition to its power-generating capacity, the Camshaft can affect your car's fuel efficiency. The Camshaft has lobes that exert pressure on the valves in an engine. The shape of the lobes is a key factor in affecting the performance of the engine. The lobe opens the intake valve at the top of the combustion stroke. The force of the piston forces out the gases. The lobe closes when the piston reaches the top of the cycle. This is how the Camshaft works in the engine. The Camshaft's function is to open and close valves at the top of each cylinder. There are at least two valves in each cylinder. One valve draws in combustible air and fuel mixture and forces the piston downward in the cylinder. The other valve opens to release exhaust gases. Once the combustion process has started, the camshaft opens and closes the valves. This is how the engine responds to fuel and air.

The role of the camshaft?

The role of the car camshaft is to control the opening and closing of the valve. A camshaft is a component in a piston engine. Although the speed of the camshaft in a four-stroke engine is half of that of the crankshaft, it usually still has a high speed and needs to withstand a lot of torque. Therefore, the design requires high strength and support for the camshaft, and its material Generally high-quality alloy steel or alloy steel. The following is the relevant content of the car camshaft:
1. If the oil supply pressure of the oil pump is insufficient due to the long-term use, or the lubricating oil channel is blocked, the lubricating oil cannot reach the camshaft, or the tightening torque of the bearing cap fastening bolts is too large, so that the lubricating oil cannot enter the camshaft clearance. will cause abnormal wear of the camshaft;
2. The abnormal wear of the camshaft will cause the gap between the camshaft and the bearing seat to increase, and the axial displacement will occur when the camshaft moves, resulting in abnormal noise. Abnormal wear will also cause the gap between the drive cam and the hydraulic tappet to increase, and the cam will collide with the hydraulic tappet when it is combined, resulting in abnormal noise;
3. When installing the bearing cover, pay attention to the direction arrows and position numbers on the surface of the bearing cover, and use the torque wrench to tighten the bearing cover fastening bolts in strict accordance with the specified torque.

What is the function of the camshaft in the engine?

A single overhead camshaft means there is only one camshaft, and a double overhead camshaft means there are two, which is too straightforward to explain.
The single overhead camshaft uses a convex root shaft on the cylinder head to directly drive the intake and exhaust valves. It has a simple structure and is suitable for high-speed engines.
. The side camshaft generally used in the past, that is, the camshaft is on the side of the cylinder, is directly driven by the timing gear. In order to convert the rotation of the camshaft into the reciprocating motion of the valve, a valve lifter must be used to transmit power. In this way, there are many parts in reciprocating motion, and the inertial mass is large, which is not conducive to the high-speed motion of the engine. Moreover, the slender tappet has a certain elasticity, which is easy to cause vibration, accelerate the wear of parts, and even make the valve out of control.
The overhead double camshaft is equipped with two camshafts on the cylinder head, one is used to drive the intake valve and the other is used to drive the exhaust valve. The use of double overhead camshafts does not require high design requirements for camshafts and valve springs. It is especially suitable for hemispherical combustion chambers with V-shaped valves, and is also easy to use with four-valve valve trains.

The importance of camshafts

A camshaft is a component in a piston engine. Its function is to control the opening and closing of the valve. Although the speed of the camshaft in a four-stroke engine is half of that of the crankshaft (in a two-stroke engine, the speed of the camshaft is the same as that of the crankshaft), but usually its speed is still very high, and it needs to withstand a lot of torque, so the design of The camshaft has high requirements in terms of strength and support, and its material is generally special cast iron, and occasionally forgings are used. Since the law of valve motion is related to the power and running characteristics of an engine, the design of the camshaft occupies a very important position in the design process of the engine.

Common transmission method between camshaft and crankshaft

Common transmission methods between the camshaft and the crankshaft include gear transmission, chain transmission and toothed belt transmission. The transmission between the lower camshaft and the middle camshaft and the crankshaft is mostly driven by cylindrical timing gears. Generally, only one pair of gears is needed to drive from the crankshaft to the camshaft. If the diameter of the transmission gear is too large, an additional intermediate gear can be added. Idler. In order to mesh smoothly and reduce working noise, the timing gears are mostly helical gears.
The chain drive is commonly used between the overhead camshaft and the crankshaft, but its working reliability and durability are not as good as the gear drive. Toothed tapes are widely used instead of drive chains on high-revving engines, but chain drives are still used on some high-power engines. Toothed tape has the characteristics of low noise, reliable operation and low cost.
For DOHC, generally the exhaust camshaft is driven by the crankshaft through a timing toothed belt or chain, the intake camshaft is driven by the exhaust camshaft through a metal chain, or both the intake camshaft and the exhaust camshaft are driven by the crankshaft. Driven by the crankshaft via toothed belts or chains.

How does a car camshaft work?

The continuous rotation of the car camshaft pushes the valve lifter to move up and down, thereby controlling the opening and closing of the valve. By changing the curve of the camshaft, the valve opening and closing time can be precisely adjusted. The symptoms of car camshaft failure are as follows:
1. The car has high-pressure fire, but the starting time is long, and the car can finally run;
2. During the starting process, the crankshaft will be reversed, and the intake manifold will be backfired;
3. The idling speed of the car is unstable and the vibration is serious, which is similar to the failure of the car lacking cylinder;
4. The car will have high fuel consumption, excessive exhaust emissions, and the exhaust pipe will produce unpleasant black smoke emissions.
