Specifications and maintenance of Nissan B11 engines

The B series engines were 4-stroke, 4-cylinder, and inline engines.

• Displacement: The total volume of all the cylinders in the engine was 1.2 liters (1200cc), which allowed for the combustion of air and fuel to create power.
• Bore and stroke: Each cylinder had a diameter (bore) of 72 millimeters, and the pistons moved 73 millimeters up and down (stroke) in the cylinder.
• Firing order: The cylinders ignited in the order of 1-3-4-2, which helped the engine run smoothly and efficiently.
• Compression ratio: The ratio of the total volume of the cylinder at the bottom of the stroke (BDC) to the volume at the top of the stroke (TDC) was 9.0:1 to 9.5:1. This means that the air-fuel mixture was compressed 9 to 9.5 times before being ignited by the spark plug, which helped the engine run more efficiently.
• Valve timing: The intake and exhaust valves opened and closed at specific times during the engine's 4-stroke cycle to allow for proper airflow and combustion. Intake valves opened at 0° and closed at 38° (degrees after top dead center) in the engine cycle. Exhaust valves opened at 80° and closed at 0° in the cycle.
• Crankshaft main bearing journals: The crankshaft's main supporting pieces measured either 55, 60, or 65 millimeters in diameter, depending on the engine's specific version.
• Connecting rods: The B11 engine's connecting rods were either 135, 137, or 140 millimeters long.
• Piston: The piston diameter was 72 millimeters, which matched the cylinder bore, and the height of the piston was 86 millimeters.
• Valves: Each cylinder had 2 intake valves and 2 exhaust valves, with each valve measuring 41 millimeters for intake and 34 millimeters for exhaust.
• Camshaft: The camshaft controlled the opening and closing of the valves. It was located in the front of the engine and had 1.5 millimeters of valve clearance (the gap between the valve and the engine block) for each valve. The camshaft was driven by a timing belt, which ensured that it was synchronized with the crankshaft and the other engine parts.

Nissan B11 engine maintenance is important for durability and reliability. Here's how to keep it in good shape:

• Regular oil changes: The engine oil should be changed every 5,000 kilometers or at least twice a year. This will keep the oil filter clean and remove contaminants. Using quality oil is needed to lubricate and protect the engine parts.
• Air filter replacement: The air filter should be changed every 20,000 kilometers or once a year. This allows for proper airflow into the engine and traps dirt and debris. A clean air filter can improve engine performance and fuel efficiency.
• Regular spark plug replacement: Spark plugs should be changed every 40,000 kilometers or according to the schedule in the owner's manual. Spark plugs ensure the air-fuel mixture ignites evenly. Worn plugs can cause misfires, poor fuel efficiency, or rough idling. The valve clearance on the B11 engine should be checked and adjusted every 40,000 kilometers or 24,000 miles. This ensures the intake and exhaust valves open and close correctly, optimizing engine performance and efficiency.
• Regular coolant flush: The cooling system needs a flush every 80,000 kilometers or 4 years. This removes buildup and ensures the engine stays at the right temperature. The coolant level should be checked regularly, and the hoses and radiator should be inspected for leaks or damage.
• Regular tire rotation: Rotating the tires every 10,000 kilometers helps them wear evenly. This maintains good traction and handling. Tire pressure should also be checked monthly, and the alignment should be adjusted as needed.
• Regular vehicle inspection: A qualified technician should inspect the vehicle every 20,000 kilometers or yearly. This checks the brakes, suspension, lights, and other important parts for safety and reliability.
