The engine is one of the most important parts of a car and a failure can cause serious problems in the operation of the car. Therefore, if there are signs of an engine malfunction, urgent action is required. In this article, we will consider the main methods and tools for diagnosing a car engine.
When is a vehicle engine diagnostic required?
The malfunction warning light is on, the engine is running intermittently, extraneous sounds have appeared in the engine, a strange smell has appeared in the cabin, the engine is smoking – all these are signs of a possible engine malfunction that require immediate attention. There may be other symptoms that must be taken into account in order to determine the cause of the malfunction.
How is the basic diagnosis of the car engine
Basic vehicle engine diagnostics can be carried out manually using tools such as calipers, micrometers and pressure gauges, as well as special devices such as compression gauges and vacuum gauges. One of the most important diagnostic methods is to check the engine oil for contamination and the presence of metal particles.
What Are The Features Of Car Computer Diagnostics
Computer diagnostics of the car allows for a more accurate and detailed check of the engine. For this, special equipment is used, which is connected to the diagnostic connector of the car. Using computer diagnostics, you can check the status of various vehicle systems, including the ignition system, fuel system, cooling system, and exhaust system. In addition, computer diagnostics allows you to read errors that may occur in the engine control system and determine their cause.
What Are The Differences Of Diesel Engine Diagnostics
A diesel engine differs from a gasoline engine in that it uses diesel fuel and has a higher compression ratio. This means that specialized equipment and methods are required to diagnose a diesel engine.
One of the methods for diagnosing a diesel engine is a compression test. For this, a compression gauge is used, which allows you to measure the pressure in each cylinder of the engine. If the pressure in one or more cylinders is too low, this may indicate a malfunction of the piston rings or the cylinder head.
Another method for diagnosing a diesel engine is to check the fuel injection system. To do this, special devices are used, such as testers and controllers, which allow a detailed check of the injection system and identify faults.
Diagnosis of a Car Engine Using an Endoscope
An endoscope is a special device that allows you to inspect the internal parts of the engine, such as pistons, valves, liners, etc. It is a very useful tool for diagnosing faults such as worn piston rings, damaged valves, etc. The endoscope can be used as an additional tool along with other diagnostic methods.
In conclusion, car engine diagnostics is a very important process that allows you to determine the causes of malfunctions and take appropriate measures. Basic diagnostics can be carried out manually using tools, while computer diagnostics allow for a more accurate check. Diesel engine diagnostics require specialized equipment and methods, and an endoscope can be used as an additional tool. If there are signs of an engine malfunction, contact a specialist to diagnose and fix the problem.
