What are the signs of engine crankshaft failure?

The symptoms of engine crankshaft failure are: no high-voltage electricity, no fuel injection, no starting, and the engine fault light on the instrument panel is on. The function of the engine crankshaft is to bear the force transmitted by the connecting rod and convert it into torque, output it through the crankshaft and drive other accessories on the engine. The crankshaft is subjected to the combined action of centrifugal force of rotating mass, periodic gas inertia force and reciprocating inertia force, which makes the crankshaft bear the bending and torsional load. The function of the engine is to transform the heat energy of gasoline and diesel into mechanical energy by expanding the gas after combustion in the sealed cylinder.

Where is the crankshaft of the car engine?

The main rotating parts of the engine, after the connecting rod is installed, can undertake the up and down (reciprocating) motion of the connecting rod into circular (rotating) motion. It is an important part of the engine. Its material is made of carbon structural steel or nodular cast iron. There are two important parts: main journal, connecting rod journal and others. The main journal is installed on the cylinder block, the connecting rod journal is connected with the large head hole of the connecting rod, and the small head hole of the connecting rod is connected with the cylinder piston. It is a typical crank slider mechanism. The lubrication of the crankshaft mainly refers to the lubrication of the bearing bush between the crankshaft and the rocker arm and the lubrication of the fixed points at both ends. The rotation of the crankshaft is the power source of the engine. It is also the source power of the whole mechanical system

Materials of automobile crankshaft

Steel crankshafts are mainly made of steel materials, which determine the main quality of crankshafts. In addition, the processing technology and processing accuracy. Steel Crankshafts generally use fillet rolling technology. The accuracy of crankshaft industry is invisible to the naked eye.

What is the crankshaft made of

The crankshaft is generally composed of main journal, connecting rod journal, crank, balance weight, front end and rear end. A main journal, a connecting rod journal and a crank form a crank. The number of cranks of the crankshaft is equal to the number of cylinders (in-line engine); The number of cranks of V-type engine crankshaft is equal to half of the number of cylinders.

What is the engine crankshaft

Crankshaft is an important part of engine. It bears the force from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine. The crankshaft is subjected to the combined action of centrifugal force of rotating mass, periodic gas inertia force and reciprocating inertia force, which makes the crankshaft bear the bending and torsional load. Therefore, the crankshaft is required to have sufficient strength and stiffness, and the journal surface needs to be wear-resistant, work evenly and have good balance.

Crankshaft, "invisible" auto parts

The crankshaft is the main rotating part of the engine. After the connecting rod is installed, it can undertake the up and down (reciprocating) motion of the connecting rod and become a circular (rotating) motion.

30% engine crankshaft weight reduction? Honda did this

Vehicle lightweight is an effective way to improve fuel efficiency and reduce vehicle carbon emissions. The International Energy Agency said that about 24% of global carbon dioxide emissions came from transportation, including roads, railways, aviation and shipping, of which road vehicles were the biggest "culprit".

FAW Volkswagen quality tour phase IV South China Station ends perfectly

How to evaluate the quality of a car? We should not only look at the configuration and function, but also focus on the process and reliability of products, as well as the enterprise's own quality standards and management ability. In this regard, a "good car" is not determined by all kinds of fashionable external "equipment", but also depends on profound "internal skills".
