Why Does Engine Oil Increase and Emulsify?

Reasons for engine oil increase and emulsification: 1. Oil increase: When the engine frequently operates under low-temperature and low-speed conditions, the oil temperature doesn't rise sufficiently. Water and gasoline mixed in the oil fail to evaporate, accumulating over time and causing the oil level to rise. 2. Oil emulsification: The essence of oil emulsification is the mixing of water and oil, resulting in a white emulsion. Causes of oil emulsification include water vapor in the crankcase condensing into water and seeping into the oil under low temperatures, and ethanol gasoline's tendency to absorb moisture, bringing water from the air into the engine cylinders. When a car operates for extended periods under low-temperature and low-speed conditions, water cannot evaporate and remains trapped in the oil, leading to emulsification issues when mixed together.

What is the minimum engine displacement for motorcycles to be allowed on highways?

Motorcycles powered by fuel engines with a displacement exceeding 50cc are permitted on highways. Below are specific regulations for motorcycles on highways: 1. Helmet: Riders must wear a helmet while driving on highways. 2. Speed: Motorcycle speed should be maintained between 60—80 km/h, carrying passengers is prohibited, and riding must be done in the rightmost lane. 3. Highway restrictions: Pedestrians, non-motorized vehicles, tractors, wheeled special machinery vehicles, articulated buses, full trailers, and other motor vehicles with a design speed below 70 km/h are not allowed on highways. 3. Speed regulations: Highways must indicate lane speed limits, with maximum speed not exceeding 120 km/h and minimum speed not below 60 km/h.

What are the symptoms of a broken supercharger?

Turbine supercharger's condition will affect fuel economy, engine output power, and engine emissions. The following are the symptoms of a broken supercharger: 1. Poor sealing of the turbine supercharger impeller shaft: Blue smoke from the exhaust at idle, sometimes light and sometimes heavy. No blue smoke while driving, but engine oil is consumed. 2. Severe blockage of the exhaust gas recirculation pipe: Blue smoke from the exhaust at idle and while driving, worse when accelerating, with significant engine oil consumption. 3. Abnormal noise: The engine makes abnormal noises while driving, and the exhaust pipe emits a lot of blue smoke. This is caused by wear or aging of piston rings, cylinder walls, or valve oil seals;

What does ECU mean when displayed on a car?

ECU stands for Electronic-Control-Unit, also known as the vehicle computer or onboard computer. Here is an introduction to ECU: 1. Composition of ECU: The ECU is similar to a regular computer, consisting of a microprocessor (CPU), memory (ROM, RAM), input/output interfaces (I/O), analog-to-digital converters (A/D), as well as shaping, driving, and other large-scale integrated circuits. 2. Functions of ECU: It has self-diagnosis and protection capabilities. When a system failure occurs, it can automatically record the fault code in RAM and take protective measures to read substitute programs from the inherent programs to keep the engine running. At the same time, these fault messages will be displayed on the dashboard and remain lit, allowing the owner to promptly identify the issue and drive the car to a repair shop.

What is the process for obtaining temporary license plates?

Temporary license plate application process is as follows: 1. Fill out the application form: When applying for temporary license plates, the vehicle owner needs to complete a temporary license plate application form based on their personal information. 2. Receive a queue number: After completing the form, the staff will give you a queue number. Simply wait in line according to this number to process the temporary license plate service. 3. Submit documents: When your turn comes, proceed to the dedicated window for temporary license plate services. Present the required documents and the completed temporary license plate application form to the staff. The materials required for applying for temporary vehicle license plates are as follows: 1. Vehicle documents: Original vehicle certification, photocopy (import vehicles require import certificates). 2. Traffic documents: Original third copy of compulsory traffic insurance, photocopy. 3. Owner's personal information: Original owner identification, photocopy.

Why Was the Rotary Engine Phased Out?

The rotary engine was phased out due to its high production process and cost requirements. High cost of rotary engines: Because rotary engine technology is more precise, the manufacturing process demands higher standards, resulting in higher costs. Its unique mechanical structure also makes this engine difficult to maintain. Today, Mazda in the automotive industry is very familiar with this technology, but it is far from being widely adopted. Additionally, rotary engines consume more fuel. Power output: The engine's power output shaft is positioned higher, making vehicle layout inconvenient. Moreover, the engine can only use spark ignition and cannot employ compression ignition, thus making it incompatible with diesel fuel. Not only that, because rotary engines are very rare, maintenance costs are not low. Using a rotary engine to power vehicles remains a challenging technology rather than a mass-produced product, or even a concept car. Although it can be used, it is difficult to apply as a mature technology.
