Isuzu 4BC2 Engine: Specs, Configuration, Oil, and Service Intervals

Isuzu 4BC2 Engine Specs

The Isuzu 4BC2 engine is a popular diesel engine used in various applications, including trucks, buses, and industrial equipment. Known for its reliability and durability, this engine has become a preferred choice for many industries. In this article, we will explore the engine configuration, engine oil specifications, and service intervals for the Isuzu 4BC2 engine.

Engine Configuration

The Isuzu 4BC2 engine is a four-cylinder, water-cooled diesel engine. It has a displacement of 3.3 liters, which means each cylinder has a displacement of approximately 825cc. The engine features an overhead valve (OHV) design, with two valves per cylinder. This configuration allows for efficient combustion and improved power output.

The compression ratio of the Isuzu 4BC2 engine is 17.5:1, which contributes to its fuel efficiency. It also has a direct fuel injection system, ensuring precise fuel delivery and optimal performance. With a maximum power output of around 86 horsepower at 3,200 rpm and a torque of 206 Nm at 2,000 rpm, this engine provides sufficient power for various applications.

Engine Oil Specs

Choosing the right engine oil is crucial for maintaining the performance and longevity of the Isuzu 4BC2 engine. Here are the recommended engine oil specifications:

• Viscosity: The engine oil should have a viscosity of SAE 15W-40. This viscosity rating ensures proper lubrication in both cold and hot weather conditions.
• API Classification: The engine oil should meet the API CF-4 or higher classification. This classification indicates that the oil has the necessary additives to protect the engine from wear, deposits, and corrosion.
• Oil Capacity: The Isuzu 4BC2 engine has an oil capacity of approximately 7.5 liters. It is important to check the oil level regularly and maintain it within the recommended range.

Service Intervals

Regular maintenance is essential to keep the Isuzu 4BC2 engine in optimal condition. Here are the recommended service intervals:

• Oil Change: The engine oil should be changed every 5,000 kilometers or every three months, whichever comes first. Regular oil changes help remove contaminants and ensure proper lubrication.
• Oil Filter Replacement: The oil filter should be replaced during each oil change. This helps maintain the cleanliness of the oil and prevents debris from circulating in the engine.
• Air Filter Replacement: The air filter should be inspected and replaced if necessary every 10,000 kilometers or every six months. A clean air filter ensures proper air intake and protects the engine from dust and debris.
• Fuel Filter Replacement: The fuel filter should be replaced every 20,000 kilometers or every year. A clean fuel filter prevents contaminants from reaching the engine and ensures efficient fuel delivery.
• Regular Inspections: It is recommended to have the engine inspected by a qualified technician every 10,000 kilometers or every six months. This allows for early detection of any potential issues and ensures timely maintenance.

Following these service intervals and using the recommended engine oil will help maximize the performance and lifespan of the Isuzu 4BC2 engine. Regular maintenance is key to keeping the engine running smoothly and avoiding costly repairs in the long run.
