Tuk-tuks, also known as auto rickshaws, are three-wheeled vehicles commonly used for public transportation and goods delivery in many countries. The tuktuk engine is one of the most important parts of the tuk-tuk, which provides power and drives the vehicle. There are different types of engines available in tuk-tuks, each with its own advantages and disadvantages. Here are some common types of engines found in tuk-tuks:
Gasoline Engines
These are the most common engines found in tuk-tuks. They are known for their power and performance. Gasoline engines provide a smooth and fast ride, making them suitable for long distances and hilly areas. However, they are less fuel efficient and emit more pollutants compared to other types of engines.
Diesel Engines
Diesel engines are more fuel efficient than gasoline engines. They also provide more torque, which is useful for carrying heavy loads or transporting more passengers. However, diesel engines can be noisier and produce more emissions, particularly nitrogen oxides and particulate matter.
Electric Motors
In recent years, electric motors have emerged as a sustainable alternative in tuk-tuk engines. Electric motored tuk-tuks are quiet, have low operating costs, and produce zero emissions at the point of use. However, these electric motors have limitations, such as lower power compared to internal combustion engines, limited range due to battery capacity, and longer charging times.
Hybrid Engines
Hybrid engines combine traditional internal combustion engines (gasoline or diesel) with electric motors. This combination allows for improved fuel efficiency, reduced emissions, and regenerative braking. Hybrid engines in tuk-tuks offer a balance between power and sustainability, making them suitable for urban environments with congested traffic.
Four-Stroke Engines
These engines use a four-stroke cycle to convert fuel into mechanical energy. Four-stroke engines are known for their fuel efficiency and lower emissions compared to two-stroke engines. They are commonly used in gasoline-powered tuk-tuks.
Two-Stroke Engines
Two-stroke engines complete the power cycle in two strokes of the piston, resulting in higher power output for their size. Two-stroke engines are simpler and cheaper to manufacture, making them suitable for low-cost tuk-tuks. However, they are less fuel efficient and produce more emissions compared to four-stroke engines.
Tuk-tuk specifications vary depending on the region, usage, and design requirements. Here are some common tuk-tuk specifications:

Some tuk-tuks use petrol, while others use diesel or LPG (liquefied petroleum gas) as their fuel source.
Max Power Output
Generally, the maximum power output of a tuk-tuk engine is between 40 to 60 horsepower (29 to 44 kW).
Max Torque
The maximum torque for a tuk-tuk engine is approximately 100 to 150 Nm (Newton meters).
Transmission
Tuk-tuks commonly have a manual transmission system with 4 to 5 gears; however, some modern tuk-tuks have an automatic transmission system.
Seating Capacity
The seating capacity for a tuk-tuk varies from 2 to 6 passengers, together with the driver.
Luggage Capacity
Generally, a tuktuk can carry 50 to 100 kg of luggage, depending on the model.
Dimensions
Tuk-tuk dimensions such as length, width, and height can vary. However, the typical length is 2.5 to 3 meters, width between 1.3 to 1.5 meters, and height between 1.5 to 2 meters.
Brakes
Tuk-tuks are fitted with hydraulic disc brakes or drum brakes on both the front and rear wheels.
Suspension
The suspension system of a tuk-tuk is typically made of coil springs, shock absorbers, and leaf springs.
Tires
Tuk-tuks are fitted with tires that are typically 12 to 15 inches in diameter, and the tire size is generally 4.00-8 to 155/70-R13.
Electronics
Tuk-tuks are equipped with basic electronic components such as a battery, starter motor, alternator, and ignition system. Modern tuk-tuks may also come with additional electronic features such as GPS, air conditioning, and electric starters.
Tuk-tuk engines are an important component that needs regular maintenance to ensure optimal performance and durability. Here are some common maintenance tips:
Engine Oil Change
Regularly changing the engine oil is an important part of maintaining a tuk-tuk engine. Engine oil should be changed every 3,000 to 5,000 kilometers or as recommended by the manufacturer. Engine oil helps to lubricate engine parts and reduces friction, thereby preventing wear and tear. Additionally, oil filters should be replaced along with the engine oil to ensure clean oil supply to the engine.
Air Filter Maintenance
The air filter of a tuk-tuk engine should be cleaned and replaced regularly. A clean air filter allows proper airflow into the engine and prevents dirt and debris from entering the engine. Dirty air filters can cause engine inefficiency and reduce fuel economy. It is recommended to clean the air filter every 1,000 kilometers or more frequently in dusty environments.
Spark Plug Inspection
Tuk-tuk engines that use petrol require regular inspection and replacement of spark plugs. Spark plugs ignite the air-fuel mixture in the engine cylinders. Worn-out or faulty spark plugs can cause engine misfires, rough idling, and reduced fuel efficiency. Spark plugs should be checked every 10,000 to 15,000 kilometers or as recommended by the manufacturer. If worn out, they should be replaced to ensure smooth engine operation.
Fuel System Maintenance
The fuel system, including fuel filters and injectors, should be checked and cleaned regularly. Clean fuel filters prevent impurities and contaminants from entering the engine, while clean fuel injectors ensure proper fuel atomization for efficient combustion. Fuel filters should be changed every 20,000 to 30,000 kilometers, while fuel injectors can be cleaned using fuel additive treatments or professional cleaning equipment.
Cooling System Inspection
The cooling system, which consists of a radiator, coolant, and thermostat, should be checked to prevent engine overheating. The coolant level and quality should be checked regularly, and any leaks or damage in the cooling system should be repaired promptly. The coolant should be changed every 40,000 to 50,000 kilometers or as recommended by the manufacturer to maintain its effectiveness in temperature regulation.
Valve Clearance Adjustment
The valve clearance of the tuk-tuk engine should be inspected and adjusted periodically. Proper valve clearance ensures optimal engine performance and fuel efficiency. Valve clearance should be checked every 20,000 to 30,000 kilometers or as specified by the manufacturer. Any necessary adjustments should be done to meet the recommended specifications.
Belts and Hoses Inspection
The various belts and hoses of the tuk-tuk engine should be checked for wear, cracks, or damage. This includes the timing belt, fan belt, and various hoses in the engine bay. Any signs of wear or damage should be promptly replaced to prevent engine component failure.
