The Toyota 22R engine is often referred to as one of the most reliable and durable engines ever produced. Introduced in the late 1970s, it has powered various Toyota models for decades. Owners report that these engines regularly exceed 300,000 miles, with some even reaching half a million miles with proper maintenance.

Mercedes-Benz OM617 diesel engine

The Mercedes-Benz OM617 diesel engine, a stalwart of the 1980s, is known for its durability. It is not uncommon to find vehicles equipped with this engine still running smoothly with over 500,000 miles on the odometer. This engine’s reputation for durability has made it a favorite among enthusiasts.

Volvo Redblock Engine

Volvo’s Redblock engine family, produced from the late 1960s to the 2000s, is renowned for its durability. Many of these engines have reached 300,000 miles or more, a testament to Volvo’s commitment to reliability.

Honda B-series engine

Honda B-Series engines, which are found in a variety of models, are known for their durability and performance. These engines have earned a reputation for running smoothly even after crossing the 300,000-mile threshold. Proper maintenance remains the key to their longevity.

Ford Windsor V8 engine

The Ford Windsor V8 engine, which has been widely used in various Ford models since the 1960s, is a classic example of American muscle. It’s not uncommon to find these engines with over 200,000 miles still running great. Their continued popularity among collectors and enthusiasts is a testament to their long-lasting qualities.

The numerous advantages of electric motors include:

• Reduced or no emissions;
• Minimal noise impact;
• Reduced dependence on oil and petroleum products;
• Flexibility in vehicle design.

Despite their many advantages, electric motors are not without limitations. The cost of producing batteries is rising, and there are concerns about mining.

In addition, the production of batteries pollutes the environment more than internal combustion engines. However, future technological developments are likely to make battery mining and production more environmentally friendly and more efficient, leaving current ICE developments behind.

Automobiles have come a long way, and one of the main areas of development is the development of new types of automotive engines.

Innovation continues, and so far, internal combustion engines are still the longest-lasting and most common in the world. and although they are starting to be phased out in advanced countries, ICEs will continue to be used in third world countries for a long time to come.

In the future, we will see innovations in all three automotive engine configurations. Whether we have more electric vehicles or other types of engines, emissions and efficiency will be at the heart of any new development.

When you need to diagnose the car engine

A warning light is on, the engine is running intermittently, there are strange sounds in the engine, there is a strange smell in the cabin, the engine is smoking – all these are signs of a possible engine malfunction that require immediate intervention. There may be other symptoms that need to be taken into account to determine the cause of the malfunction.

How to perform basic car engine diagnostics

Basic car engine diagnostics can be performed manually using tools such as calipers, micrometers, and pressure gauges, as well as special devices such as a compressometer and vacuum gauge. One of the most important diagnostic methods is to check the engine oil for contamination and the presence of metal particles.

Features of computer car diagnostics

Computerized vehicle diagnostics allows for a more accurate and detailed engine check. This is done using special equipment that is connected to the vehicle’s diagnostic connector. With the help of 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 management system and determine their cause.

Differences in 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 method of diagnosing a diesel engine is to check compression. To do this, a compressometer is used 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 cylinder head.

Another method of diagnosing a diesel engine is to check the fuel injection system. For this purpose, special devices are used, such as testers and controllers, which allow for a detailed check of the injection system and identify malfunctions.

Diagnosing a car engine with an endoscope

An endoscope is a special device that allows you to inspect the internal parts of an engine, such as pistons, valves, liners, etc. It is a very useful tool for diagnosing malfunctions such as piston ring wear, valve damage, 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 with the help of tools, while computer diagnostics allows for a more accurate check. Specialized equipment and methods are required to diagnose a diesel engine, and an endoscope can be used as an additional tool. If there are signs of engine malfunction, you should contact a specialist to diagnose and fix the problem.

This power unit is the most commonly used today. It began its life as a single-cylinder two-stroke engine in the 19th century and has evolved into various configurations. Manufacturers continue to improve this type of engine to increase power and efficiency to compete with hybrid and electric installations.

ICEs generate power by burning fuel in a controlled chamber. The power is then transmitted to the wheels through a transmission. This is a brief description of the operation of any gasoline or diesel engine.

Among the three types of automobile engines listed above, this is the only type that uses exclusively fossil fuels – oil. This can be gasoline, gas, or diesel, depending on the type of combustion. This brings us to the two main types of internal combustion engines.

Gasoline engines

The roaring sound you often hear in supercars comes from these engines, albeit with some modifications. Most cars with internal combustion engines are equipped with them.

This type of engine has cylinders or combustion chambers where the air-fuel reaction takes place. Injectors (or a carburetor in older engines) supply fuel to the chamber, and intake valves allow a certain amount of air to mix with the fuel.

The spark plug then ignites the mixture, causing it to burn. This reaction releases enormous energy that pushes the piston in the chamber downward. This action turns the flywheel through the connection to the crankshaft and then transmits the torque to the wheels.

Engines with an ignition system

At this point we have to list the components for clarity and easy distinction from other types of automotive engines. The components are as follows:

• Cylinders: The fuel combustion process takes place in these chambers
• Intake valves: Let air into the combustion chamber
• Injectors or carburetors: Inject metered fuel into the chamber
• Spark plugs: Ignite the fuel-air mixture
• Exhaust valves: Remove the burnt mixture
• Pistons: Transfer downwardly directed energy to the crankshaft
• Crankshaft: Converts the vertical motion of the pistons into a circular motion.
• Flywheel: Transfers power from the engine and connects to the transmission.
• The main component of engines with an ignition system is the spark plug. Without it, there is no combustion and no power generation.

These powerplants use a lighter form of oil, gasoline, to create the necessary power. As a result, they burn faster and require more frequent refueling. Now let’s see how things are going with the diesel analog.

Compression-ignition engines

This type is similar to a spark ignition engine. It uses a combustion chamber and all other components, but no spark plugs.

The process of igniting the fuel here is due to a combination of heat, air and pressure. As soon as the pressure from the piston reaches a predetermined value, the fuel-air mixture ignites.
