ITI Diesel Mechanic Interview Questions and Answers

2 stroke and 4 stroke engines differ in their operation and design.

• 2 stroke engines complete a power cycle in 2 strokes of the piston, while 4 stroke engines complete it in 4 strokes.

• In a 2 stroke engine, the intake and exhaust occur simultaneously, while in a 4 stroke engine, they occur separately.

• 2 stroke engines have a simpler design with fewer moving parts, while 4 stroke engines are more complex.

• 2 stroke engines are generally lighter and have higher power-to-weight ratio...read more

A diesel mechanic is a professional who specializes in the maintenance and repair of diesel engines.

• Diesel mechanics diagnose and repair problems with diesel engines.

• They perform routine maintenance on diesel engines to ensure they are running efficiently.

• They use a variety of tools and equipment to repair and replace parts of diesel engines.

• Diesel mechanics may work on a variety of vehicles and equipment, including trucks, buses, boats, and generators.

• They must have a strong...read more

The firing order of a diesel engine depends on the number of cylinders and their arrangement.

• The firing order is the sequence in which the cylinders fire.

• It is important for proper engine performance and timing.

• For example, a 4-cylinder engine may have a firing order of 1-3-4-2.

• A V8 engine may have a firing order of 1-8-4-3-6-5-7-2.

A diesel engine is an internal combustion engine that uses compression ignition to burn fuel.

• Diesel engines are commonly used in heavy-duty vehicles like trucks and buses.

• They are more fuel-efficient than gasoline engines and produce less carbon dioxide emissions.

• Diesel engines have a higher compression ratio than gasoline engines, which allows them to generate more power.

• They are also known for their durability and longevity.

• Common diesel engine manufacturers include Cummins...read more

The firing order of a 6-cylinder engine determines the sequence in which each cylinder fires.

• The firing order is specific to each engine model and can be found in the manufacturer's documentation.

• It is important to follow the correct firing order to ensure proper engine performance and avoid damage.

• The firing order is usually indicated by a numerical sequence, such as 1-5-3-6-2-4.

• Each cylinder fires at a specific point in the engine's rotation, determined by the crankshaft po...read more

The firing order of Ashok Leyland engines is determined by the specific engine model.

• The firing order can vary depending on the number of cylinders and the engine configuration.

• For example, the firing order of a 4-cylinder Ashok Leyland engine may be 1-3-4-2.

• It is important to consult the engine manual or manufacturer specifications for the accurate firing order.

Engine stroke refers to the movement of the piston within the cylinder during the combustion process.

• Engine stroke is the distance the piston travels from top dead center (TDC) to bottom dead center (BDC) or vice versa.

• There are four strokes in a four-stroke engine: intake, compression, power, and exhaust.

• During the intake stroke, the piston moves downward, drawing air-fuel mixture into the cylinder.

• In the compression stroke, the piston moves upward, compressing the air-fuel ...read more
