What is a 4-stroke engine? Types, Advantages, Disadvantages, Need

A 4-stroke engine is an Internal combustion engine, where four successive strokes (i.e. Suction-Compression-Power-Exhaust) completes in two revolutions of the crankshaft. In recent days the majority of automobile runs on a four-stroke cycle.

Reciprocating Engine: Overview, Types, Parts & Working

A Reciprocating Engine is a classification of the internal combustion engines in which the piston moves up and down. The top portion of the piston where valves are located is called Top dead center, while the opposite extreme down portion of the piston is called Bottom dead center.

Camshafts and Crankshafts: What Do They Do & How Do They Work?

Camshafts and crankshafts are terms you've probably heard if you've discussed internal combustion engines with your mechanic (or fellow car enthusiasts). But what is a camshaft or a crankshaft, and what do they do?

Camshaft vs Crankshaft – Difference

One notable difference between a Camshaft vs crankshaft is that the camshaft assists to actuate the inlet and exhaust valves, whereas the crankshaft helps to transform the reciprocating action of the piston into rotational motion.

Valve Overlap: Definition, Diagram, Purpose, Advantages, Disadvantages

Without valve overlap, a small amount of exhaust gases will remain in the combustion chamber which will affect the engine's performance and exhaust. Valve overlap promotes better scavenging of the gases in the engine.

Camshaft: Functions, Types, Parts, Diagram, Working

In four-stroke engines, the camshaft is responsible for the timely operation of the valves, helping to perform different processes during the engine cycle. It is driven by the engine crankshaft and sits on top of the engine.

Camshaft

camshaft, in internal-combustion engines, a rotating shaft with attached disks of irregular shape (the cams), which actuate the intake and exhaust valves of a piston and cylinder.

Understanding Camshafts

In scientific terms, it's all about the area under the curve. Just like that calculus class you wished you didn't have to take (or avoided altogether), the camshaft in your engine is largely based on the same mathematical rules.

How Camshafts Work

The camshaft is critical to the basic function of an engine. Comprised of two distinct parts, the cams and the shaft, the camshaft is the element that enables valves to open. As the shaft rotates, the egg-shaped cams (or "lobes") push the valves open in sync with the crankshaft gear.

What is Camshaft Lobe Separation?

The Lobe Separation Angle (LSA) is the distance between the centerlines of the intake and exhaust lobes on the camshaft. It is measured in degrees of camshaft rotation.

What is camshaft end play?

End play is how far the camshaft moves in the engine block, from back to front. It is sometimes referred to as how far the cam will "walk."

What is the difference between a flat tappet and a roller camshaft?

Camshafts are classified by the type of lifter they use. The lobes on the cam are machined differently based on the intended lifter. Lifters are sometimes called a "follower" or "tappet." They contact the cam lobe with either a flat surface or a wheel.

How do I break in my roller camshaft and lifters?

Breaking in an enigne with a roller camshaft is important. Metal particles are created during break-in. This is the biggest issue for the bearings in the roller lifter.
