• V engine

  A V petrol engine assembly has cylinders arranged in two rows. The rows are angled in a V shape. The most common V engine assemblies have 6, 8, or 12 cylinders. The V6 engine assembly is often used in medium-sized cars. V8 engines are popular for high-performance cars and SUVs. Luxury cars and sports cars use the V12 engine assembly. The V engine assembly is more powerful than the inline engine assembly. However, the V engine assembly is heavier. This makes the petrol engine assembly more expensive.

• Flat engine

  A flat engine assembly has horizontal cylinders. Similar to the V engine assembly, the flat engine also has its cylinders arranged in two rows. However, the two rows in a flat engine are parallel and opposite to each other. Flat engine assemblies have 4, 6, or 12 cylinders. Flat 6-cylinder engines are the most common. Flat engine assemblies are low to the ground. As a result, cars with a flat engine assembly have a lower center of gravity. This makes the petrol engine assembly more stable. Flat engine assemblies also have a wider chassis. As a result, flat engines are often used in sports cars.

• Rotary engine

  Rotary engine assemblies are quite different from the other types of petrol engine assemblies. Rotary engines have triangular rotors. The triangular rotor spins in an oval housing. The rotary engine has 1 to 3 triangular rotors. Each rotor is responsible for intake, compression, combustion, and exhaust strokes. Rotary engine assemblies have fewer moving parts. As a result, rotary engines are more reliable and require less maintenance. Rotary engine assemblies are compact and lightweight. The disadvantages of rotary engines are that they are less fuel efficient and have higher emissions compared to piston engines.

Under-inflated tires cause excess rolling resistance. The engine works harder, using more fuel. Over-inflated tires reduce contact with the road and uneven wear occurs. Inspect tires monthly for cracks, bulges, or worn treads. Uneven wear may result from misalignment or suspension issues. Replace tires that are bald or damaged.

• Cooling System Checks

  The engine generates heat while running. The cooling system prevents overheating. Inspect the radiator and hoses for leaks or cracks. Monitor coolant levels in the reservoir. Top up with a 50/50 mix of antifreeze and water. Flush the system every 2-4 years to remove rust and scale build-up. This maintains cooling efficiency.

• Spark Plug Inspection

  Spark plugs ignite the air-fuel mixture in petrol engines. They need periodic checks and replacements. Examine spark plugs for signs of wear or deposits. Follow the service manual for the correct gap and heat range. Worn plugs can cause misfires and reduce engine efficiency. Replace plugs after the specified number of kilometers or years. New plugs ensure reliable ignition.

• Fuel System Maintenance

  A clean fuel system delivers the right mixture for combustion. Use quality fuel from reputable stations. Avoid low-quality additives that can damage the engine. Replace the fuel filter every 40,000 to 100,000 kilometers. A new filter prevents rust and debris from clogging injectors or the carburetor. Consider a professional fuel system clean to remove deposits. This restores optimal performance.

• Belts and Hoses

  Engine belts and hoses are important for function. Inspect them for wear and leaks. Look for cracks, fraying or glazing on belts. They drive components like the alternator and water pump. Replace faulty belts before they snap and cause damage. Check hoses for bulges, splits or leaks. They transport fluids like coolant and oil. Loose or damaged hoses can leak and cause overheating. Get faulty hoses changed.

• Regular Tune-Ups

  Regular tune-ups keep the engine running smoothly. Follow the schedule in the service manual. A technician will inspect and adjust key engine parts. They check the ignition system, timing, and emissions controls. They clean or replace air/fuel filters. Tune-ups improve fuel efficiency and reduce emissions. The engine is ensured to run at peak performance.
