The effective performance indicators of an automobile engine are based on the net power output at the crankshaft.

The work done in a unit of time is called power. When an engine cylinder completes a working cycle, the useful work done by the compressed gas on the piston in a unit of time is called indicated power.

The reason for the crankshaft oil seal falling off is this!

A few days ago, I took over the repair of a Thai Honda (local name) step-through motorcycle. The owner informed me that the engine was leaking oil and asked for help with the repair. After inspection, I determined that the left crankshaft oil seal (from the magneto) was leaking oil and informed the owner that it needed to be replaced.

Crankshaft

The material is made of carbon structural steel or ductile iron, with two important parts: the main shaft neck and the connecting rod neck (and others). The main shaft neck is mounted on the cylinder body, while the connecting rod neck connects to the big end hole of the connecting rod, and the small end hole of the connecting rod connects to the piston in the cylinder.

The engine of a car can be either transverse or longitudinal? Mid to high-end cars mostly have longitudinal engines.

In front-engine vehicles, depending on the orientation of the engine placement, they can be divided into longitudinal and transverse types. Since the methods are different, there are certainly their own advantages and disadvantages. Simply put, compact front-wheel-drive cars, most mid-size sedans, and a few luxury sedans adopt the transverse engine layout, which is mainstream.

How does the engine crankshaft dissipate heat when it frequently rubs? The principle is surprisingly simple!

The engine crankshaft's friction and heat dissipation rely on oil splashing lubrication and a specialized oil circuit system. Engine oil, also known as engine lubricant, is not only used for lubrication but also serves to dissipate heat and prevent corrosion. Heat is transferred through the oil to the radiator, which carries away the heat through the engine cooling system. Therefore, as long as the oil condition is good, it will not affect heat dissipation.

Determine whether to adjust the gauge by checking the crankshaft screws.

It is said that the second-hand car market is deep, but after being in this industry for a long time, it’s really not that complicated. We all know that the key to buying a second-hand car is to check if the car has had any accidents, if it has been flooded, if the odometer has been tampered with, and what the condition of the engine is like.
