The four-stroke internal combustion engine relies on the precise timing and operation of intake and exhaust valves to control the flow of the air-fuel mixture into the cylinder and the exhaust gases out of the cylinder. Understanding how engine valves work is key to appreciating the elegant sophistication of the four-stroke engine. The Four-Stroke Cycle … Read more
Backfiring, the loud popping or banging noises from your exhaust, is an annoying and potentially concerning issue. It’s caused by unburned fuel igniting in the exhaust system rather than the cylinder. To stop your car from backfiring, you need to address the root causes. This article will explore each of these areas in detail, outlining … Read more
To tighten a timing belt tensioner pulley, you will need basic hand tools like a ratchet, socket set, wrench, and torque wrench. It’s also essential to use jack stands for safety when working under the vehicle. The main steps involve: Helpful troubleshooting tips are provided covering issues like a still loose pulley or unusual noises … Read more
The belt tensioner is a critical but often overlooked component of the engine drive system. So how often should this small part be replaced? According to most manufacturers’ recommendations, the belt tensioner is designed to last the life of the timing or serpentine belt, typically 60,000 to 100,000 miles. Replacement intervals should be based on … Read more
A digital timing light is an essential tool for correctly setting and optimizing ignition timing on an internal combustion engine. Using a digital timing light allows you to visually inspect and adjust timing by synchronizing a strobe light flash with cylinder firing. Here is the step-by-step process for utilizing a digital timing light to check … Read more
A car backfires when accelerating due to unburnt fuel exploding in the exhaust or intake system instead of undergoing controlled combustion in the engine cylinders. This loud popping or banging backfire is caused by issues like: To diagnose and fix backfiring, one must understand its leading causes which typically stem from fuel, ignition, or exhaust … Read more
A timing belt tensioner is a device that applies precise force against the engine’s timing belt to prevent slipping and maintain accuracy of the valve and piston timing. At its core, it uses a calibrated spring and a smooth-rolling pulley to supply steady 300 to 400 pound tension against the belt. This force creates friction … Read more
Many modern vehicles use a timing belt or timing chain rather than gears to coordinate engine valve timing. So which cars opt for the more durable timing chain instead of a belt? Primarily below car models favor chains over belts. The key benefits of timing chains are longer lifespan, reduced likelihood of breaking, and suitability … Read more
No, you cannot safely operate a vehicle without a properly functioning timing belt. The timing belt is a crucial engine component that synchronizes the camshaft and crankshaft to ensure the valves open and close at the precise moment needed for proper combustion. Driving without this vital belt will cause the engine to misfire, stall, and … Read more
Timing refers to the precise moment when an engine’s valves open and close to allow air and fuel into the combustion chamber and exhaust gases out. Proper timing is crucial for smooth engine operation, performance, and longevity. There are several symptoms that can indicate the engine’s timing may be off. Let’s look at in depth … Read more
