About engine 4g93

Types of Engine 4G93

The Engine 4G93 is a petrol engine constructed by the Mitsubishi Motors Corporation. The 4G93 is a member of the 4G9 family of engines. This engine family is available in three configurations. They are:

  • 4G93 SOHC: In this configuration, the engine has a single overhead camshaft. It is equipped with a 1.8L 4G93 engine. In addition, it features a 4-cylinder cast iron block with a cast aluminum cylinder head. The fuel system used in this configuration is the electronic fuel injection system. It was produced from 1987 to 1995.
  • 4G93 DOHC: This is another configuration of the Engine 4G93. In this configuration, the engine is equipped with a double overhead camshaft. It features a 1.8L or 1.6L 4G93 engine. It also has a 4-cylinder cast iron block and a cast aluminum cylinder head. The fuel system is also the electronic fuel injection system. It was produced from 1994 to 2005.
  • 4G94: This is another configuration of the Engine 4G93. It is an obsolete engine. It has a 1.8L and 2.0L 4G93 engines. It also has a cast iron cylinder block and a cast aluminum cylinder head. The fuel system used in this configuration is the multi-port fuel injection system. The 4G94 engine was discontinued in 2009.

Specifications and maintenance of Engine 4g93

Specifications of Engine 4g93

Engine 4G93 is a 4-cylinder in-line 4-stroke cycle water-cooled gasoline engine. It is an internal combustion engine that uses gasoline as fuel. The bore and stroke of the engine are 87.5 mm and 88.0 mm, respectively. The engine has a compression ratio of 9.5:1. It has a maximum power output of 60 kW and a maximum torque of 90 Nm. The 4G93 engine has a valvetrain of DOHC (Dual Overhead Camshaft) with 16 valves. The engine also has an ignition system that uses transistorized ignition (TCI).

Maintenance of Engine 4g93

  • Engine oil and filter

    Changing the engine oil and filter regularly is important for keeping the 4g93 engine in good condition. The oil should be changed at least every 5,000 kilometers or 3,000 miles. This will remove any built-up dirt or debris from the engine. When changing the oil, it is also necessary to replace the oil filter. This will ensure contaminants do not enter the lubrication system.

  • Air filter

    The air filter should be inspected every 10,000 kilometers or 6,000 miles and replaced as needed. A clean air filter prevents dust and particles from clogging the intake system, which maintains proper airflow and avoids engine wear over time.

  • Spark plugs

    Every 20,000 kilometers or 12,000 miles, the spark plugs should be checked. They should be cleaned or replaced if they show signs of wear. Healthy spark plugs are essential for reliable ignition and efficient fuel burning in the 4g93 engine.

  • Cooling system

    The cooling system should be checked every 40,000 kilometers or 24,000 miles. The coolant level needs to be topped up, and the hoses need to be inspected for leaks or cracks. Maintaining the cooling system prevents the 4g93 engine from overheating and sustaining damage.

  • Fuel system

    Every 60,000 kilometers or 36,000 miles, the fuel system components like the fuel filter and injectors should be examined. The fuel filter needs to be replaced to ensure clean fuel flows into the engine. Cleaning or replacing the injectors ensures they deliver gasoline properly for optimal performance and efficiency.

  • Timing belt

    The timing belt must be inspected and replaced before 100,000 kilometers or 60,000 miles. A worn timing belt can cause serious engine problems. Changing it on schedule prevents expensive damage and keeps the engine's internal components synchronized correctly.

  • Throttle and idle speed

    Every 10,000 kilometers or 6,000 miles, the throttle valve should be cleaned with a suitable cleaner. The idle speed needs to be adjusted as per the manufacturer's specifications. A properly functioning throttle and correct idle speed improve the 4g93 engine's drivability and performance.

How to choose an engine 4g93

Before sourcing engine 4g93 components, retailers and wholesalers must understand their target market. Here are some factors to consider when choosing a 4g93 engine to stock.

The type and model of the 4g93 engine will affect its compatibility with various vehicles. Stock the engine types that are compatible with the majority of vehicles within the target market. For instance, the petrol 4G93 engines may not be compatible with diesel-powered vehicles, so the engine will have limited use.

Consider the transmission type supported by the engine. Manual transmissions are becoming outdated, and most vehicles are designed with automatic transmission engines. Stocking the 4g93 engines with automatic transmission will offer a better resale value as they will be in high demand.

The 4g93 engine has different specifications that affect its performance. Focus on the engine specs with better performance and fuel efficiency to meet the needs of most vehicle owners. For instance, the 4G93 DOHC MIVEC variant has better performance and efficiency compared to the SOHC variant.

Decide whether to stock new or used 4g93 engines. While used engines will have a lower price point, they will require thorough quality checks to ensure they are in good condition. New engines will require buyers to source from reputable suppliers on Chovm.com to get genuine products that are worth the value.

Check the availability of spare parts for the chosen engine type. Stock engines that have readily available spare parts to attract more clients. Many vehicle owners prefer engines that make it easy to source spare parts.

Consider the cost of the engine and its parts. Retailers can buy 4g93 engines with a competitive purchase price to sell at an attractive retail price. Wholesalers may buy the engine in bulk and enjoy great discounts from the suppliers.

How to DIY and Replace Engine 4g93

Some basic tools are required when replacing the Engine 4g93 valve cover gasket. These include:

  • Socket set
  • Torque wrench
  • Scraper
  • Ratcheting wrenches
  • Gasket maker

Follow the steps below to replace the valve cover gasket:

  • Disconnect the Battery

    For safety purposes, it is advisable to disconnect the battery before working on any part of the vehicle. This will help in preventing any electrical short circuits.

  • Remove the Air Intake

    The air intake should be disconnected from the engine and set aside. This makes it easy to access the valve cover.

  • Drain Engine Oil

    Drain the oil from the engine and remove the oil pan. This makes the valve cover accessible.

  • Remove the Old Gasket

    Use a scraper to remove the old gasket from the valve cover and the engine. Make sure not to damage the surface while doing this.

  • Install the New Gasket

    Apply a thin bead of gasket maker to the valve cover and install the new gasket. Ensure that it is properly aligned with the holes.

  • Reattach the Valve Cover

    Put the valve cover back on top of the engine and tighten the bolts in a crisscross pattern. This ensures that the gasket is evenly compressed.

  • Reconnect the Air Intake

    Air intake should be reconnected to the engine, ensuring all hoses and clamps are properly secured.

  • Refill Engine Oil

    Refill the engine with oil and ensure that there are no leaks around the valve cover.

  • Reconnect the Battery

    Reconnect the battery once all the steps are complete.
