To stop an engine from burning oil, you need to first identify the root cause, which could range from worn piston rings, valve seals, or even excessive oil entering the combustion chamber. Oftentimes, using a thicker viscosity motor oil might provide a temporary fix by slowing down the oil consumption. However, for a long-term solution, a mechanical repair is necessary. Replacing worn piston rings or valve seals, which are common culprits, will directly address the issue. It's also advisable to ensure the PCV (Positive Crankcase Ventilation) system is functioning correctly, as a malfunction can cause excessive oil consumption. Regular maintenance and timely oil changes using the manufacturer-recommended oil type can prevent the problem from reoccurring. While these measures might require upfront investment, especially if engine disassembly is needed, they are essential to stop engine oil burn and to maintain the vehicle’s performance and longevity.

The Wankel engine, also known as a rotary engine, operates on a fundamentally different principle than the traditional piston engines found in most cars. Invented by Felix Wankel in the 1950s, this engine design boasts a unique way of converting pressure into rotating motion, which makes it compact, lightweight, and capable of producing high power outputs relative to its size. At the heart of a Wankel engine is a triangular rotor that orbits in an epitrochoidal motion within a peanut-shaped, epitrochoidal housing. This motion creates three separate chambers within the housing. As the rotor orbits, these chambers change in volume, undergoing the four strokes of the Otto cycle (intake, compression, power, and exhaust) in different sections of the engine housing. During the intake phase, a mixture of air and fuel is drawn into one of the chambers as the volume of that chamber increases. The chamber's volume then decreases, compressing the mixture as the rotor continues its motion. When the mixture is fully compressed, it is ignited by spark plugs, causing a rapid expansion of gases that push against the rotor, creating rotational motion. This is the power phase. Finally, as the rotor moves further, the volume of the chamber again increases, allowing the exhaust gases to be expelled. One of the main advantages of the Wankel engine is its simplicity. With fewer moving parts than a piston engine (it lacks valves, camshafts, etc.), it is lighter and can operate smoothly at higher speeds, making it ideal for racing applications and high-performance vehicles. Its compact size also allows for greater flexibility in vehicle design. However, the Wankel engine does have drawbacks. It tends to have poorer fuel efficiency and higher emissions compared to piston engines due to incomplete combustion. The unique shape of the combustion chamber and the constant changes in volume and surface area make it more challenging to achieve complete combustion of the fuel-air mixture. Additionally, engine longevity and reliability can be issues, as the sealing around the rotor tips (apex seals) faces more wear and stress than in a conventional engine. In conclusion, while the Wankel engine offers several advantages, such as compactness, lightness, and simplicity of design, which translate into high power outputs and smooth operation, it also faces challenges in fuel efficiency, emissions, and durability. Despite these challenges, the Wankel engine has been successfully used in sports cars, notably by Mazda in their RX series, and continues to be the subject of development and refinement for future automotive applications.

To check motorcycle engine oil, first, ensure your motorcycle is upright on a level surface to get an accurate reading. For bikes with a dipstick, remove it from the oil fill hole, wipe it clean, then reinsert it without screwing it in. Pull it out again to check the oil level against the marked indicators. If your bike has a sight glass, simply look at the glass window without removing anything. The oil level should be between the minimum and maximum markers. Always ensure the engine is cool or has been off for a few minutes to allow oil to settle. Doing this regularly helps maintain engine health and performance. Adjustments or top-ups should be done according to the manufacturer's specifications, using the recommended oil type.
