Rd28 engine

Types of RD28 engines

The RD28 engine is a six-cylinder, internal combustion engine that belongs to the Nissan straight-six engine family. This engine was produced by Nissan Motor Co. Ltd. RD28 engines are a common sight in many Nissan vehicles and have quite a following because of their reliability and durability.

The RD28 engine has a cast-iron engine block with a cast-iron cylinder head. The cylinder head also has a dual overhead camshaft configuration. Each RD28 engine has an aluminum engine block and a cast-iron one. The former is used in petrol engines while the latter is used in diesel engines. The distinction between the two is made to allow for higher compression ratios in diesel engines. As mentioned earlier, the RD28 engine has a DOHC cylinder head with 2 valves per cylinder. This brings the total number of valves to 24.

There are three main types of RD28 engines. They include:

• RD28 diesel engine: The RD28 diesel engine is one of the most widely used diesel engines in the automotive industry. Its RD-series was one of the first engines produced by Nissan. The engine was first introduced in 1989 and has been used in many popular Nissan models ever since. The Nissan Patrol Y60, for example, used the RD28 diesel engine from 1990 to 1997. The Y60 was also known as the Nissan Terrano. Other notable mentions include the Nissan L35, Nissan GQ Patrol, and the Nissan L4W61. The RD28 diesel engine has been praised for its fuel efficiency and low emissions. The engine has also been used in some commercial vehicles such as the Nissan Cabstar and Nissan Interstar.
• Petrol RD28 engines: The petrol RD28 engines are not as common as the diesel variants. They were produced mainly for performance and power. The RD28 petrol engines have been used in some Nissan models such as the Nissan 300ZX and the Nissan Skyline. The Nissan Skyline GT-R with the RB26DETT engine is probably one of the most famous Nissan models that utilize the RD28 engine. The GT-R was in production from 1989 to 2002. The RD28 petrol engines are popular among car enthusiasts for their high revving nature and smooth power delivery.
• Aftermarket RD28 engines: With the growing popularity of the RD28 engine, many aftermarket manufacturers have decided to produce their own variants in a bid to capitalize on the growing interest. These aftermarket engines are often produced to a higher standard than the original Nissan engine. Some are even modified for higher performance.

Specifications and maintenance of the RD28 Engine

• Regular Oil Changes

  Engine oil lubricates the moving parts of the engine, reducing friction and wear. Over time, the oil breaks down or accumulates contaminants, necessitating a change. Follow the recommended interval for oil changes, typically every 5,000 to 7,500 miles. This ensures fresh oil is circulating to protect the engine's components.

• Air Filter Replacement

  The air filter prevents dirt and debris from entering the engine. It must be checked regularly and replaced approximately every 15,000 to 30,000 miles or more often in dusty conditions. A clean air filter ensures optimal airflow, maintaining performance and fuel efficiency.

• Spark Plug Inspection

  Spark plugs are critical for igniting the air-fuel mixture in gasoline engines. They should be inspected at the recommended intervals, usually every 30,000 to 100,000 miles. Any signs of wear, such as corrosion or electrode erosion, warrant a replacement. Healthy spark plugs ensure reliable engine starting and smooth operation.

• Coolant Flush

  The coolant regulates engine temperature. Over time, the coolant can become contaminated or lose its effectiveness. A flush, typically every 2 to 5 years, removes the old coolant and cleanses the system before adding fresh coolant. This prevents overheating and protects against corrosion.

• Tire Rotation

  Even tire wear is essential for vehicle stability and safety. Tires should be rotated, usually every 5,000 to 10,000 miles or with every oil change. This ensures they wear evenly, extending their lifespan and maintaining optimal traction.

• Brake Inspection

  Brake pads, rotors, and other components require regular checks for signs of wear or damage. Depending on driving habits and conditions, brakes should be inspected approximately every 10,000 to 20,000 miles. Timely replacements ensure the effectiveness of the braking system, promoting safety.

• Timing Belt Replacement

  The timing belt synchronizes the crankshaft and camshaft. It is crucial to adhere to the manufacturer's recommended interval for replacement, typically between 60,000 to 100,000 miles. A worn timing belt can lead to severe engine damage if it fails.

• Fuel System Cleaning

  Over time, deposits can accumulate in the fuel injectors, diminishing fuel efficiency and engine performance. A fuel system cleaning, usually every 30,000 to 60,000 miles, removes these deposits. This service can be done professionally or with fuel additives.

• Suspension Inspection

  The suspension system, including shocks and struts, should be checked for wear or damage approximately every 30,000 to 50,000 miles. Uneven roads and driving conditions can affect suspension performance. Timely replacements ensure a smooth ride and optimal vehicle handling.

• Comprehensive Vehicle Inspection

  Conducting a thorough vehicle inspection helps identify potential issues before they worsen. This involves checking various components, including the engine, transmission, brakes, tires, suspension, and electrical system. Inspecting critical parts like the engine and brakes guarantees safety and performance.
