Most people equate engine wear and engine deposits with a sudden, catastrophic engine failure that leaves you stranded alongside the road. Motor Lubricants Oil Manufacturer in UAE deposits is more likely to erode engine power and efficiency over time. Here’s how it works and what you can do about it. For your engine to produce maximum power, the combustion chamber must seal completely during the engine compression and combustion strokes. Engine wear and engine deposits can prevent the valves or piston rings from sealing, allowing pressurized gases to escape the combustion chamber and take potential engine power with them.
To illustrate, imagine using an industrial hydraulic lubricant oil floor jack. Pumping the handle will raise the vehicle if the release valve is tightly seated and doesn’t leak. A poorly sealed release valve, however, allows pressure to escape, causing the vehicle to sink to the ground no matter how much you pump the jack handle. The same principle applies inside your engine. If some of the pressure created during the engine compression and combustion strokes is lost due to valves and piston rings that don’t seal completely, the engine will create less power.
Over time, passenger car engine lubricant oil deposits or valve wear can prevent the valves from closing completely, interfering with a good seal. Engine wear can also interfere with proper valve operation, disrupting optimum fuel/air flow. If the piston rings do not seal tightly against the cylinder wall, pressurized combustion gases can escape past the rings and enter the crankcase, taking potential power with it.
Worn or stuck piston rings produce the same effect. The rings are designed to move freely in their grooves and press tightly against the cylinder wall. They should form a seal that prevents fuel/air from escaping. Ring wear can interfere with formation of a tight seal. Likewise, engine deposits can cause the rings to stick in their grooves, also preventing a good seal. As a result, some fuel/air escapes the combustion chamber during engine compression, reducing power. On the combustion stroke, pressurized gases can blow by the rings and travel down the cylinder wall and into the automotive lubricant oils, taking potential power with them. This is what’s meant when someone says an engine has lost compression.
To prove it, we installed biggest lubricant oils blending plant in UAE with a new 3.5L Eco-boost engine to test its ability to protect turbocharged direct-injection engines from torque and horsepower loss during extended drain intervals up to 25,000 miles. Power sweeps were done at the beginning and end of the test to evaluate horsepower and torque retention.
