How to Deal with Engine Oil Spraying from the Exhaust Pipe?

If the ventilation valve is aged, the only solution is to replace it, as the ventilation valve is itself a wear-prone component. It is normal for the ventilation valve to develop issues after the vehicle has been driven for a certain mileage. If the pistons, cylinder liners, or piston rings are excessively worn, replacing the corresponding components can also resolve the issue. Regular oil changes should be performed to minimize engine wear. The reasons for sudden large amounts of engine oil spraying from the exhaust pipe are as follows: 1. The crankshaft ventilation valve has aged. 2. Excessive wear of the pistons, cylinder liners, or piston rings: This can cause the engine to lose its original sealing performance, allowing engine oil to easily enter the cylinder and subsequently be expelled with the exhaust gases from the exhaust pipe. Finally, severe wear between the valve stem and valve guide can lead to oil moving up and down, which can also cause similar phenomena to occur.

What is the difference between CSS and EA211?

The differences between CSS and EA211 are mainly reflected in the following aspects: 1. Quantification. The EA211 series engines are constructed entirely from aluminum material, from the valve cover at the top of the engine to the oil pan at the bottom, all made of aluminum alloy. This significantly reduces the weight compared to the previous EA111 series. 2. Fuel consumption. The biggest advantage of EA211 is its fuel efficiency, which benefits from its cylinder deactivation system. This technology primarily works by automatically shutting down the second and third cylinders when the engine is operating under medium to low load, thereby reducing fuel consumption. Compared to models without this technology, fuel consumption per 100 kilometers is reduced by approximately 0.4L. 3. Work efficiency. As one of the core technologies of Volkswagen's MQB modular platform, the EA211 engine features dual variable valve timing for both intake and exhaust, and its direct injection system uses a 5-hole injector with an increased injection pressure of up to 200bar. These technologies collectively enhance the engine's work efficiency to a certain extent. Here is some additional information about the EA211: The EA211 engine is a new series of automotive engines under Volkswagen, including both three-cylinder and four-cylinder products. The first model to be equipped with this engine series was the Volkswagen UP.

What brand is rovelo tire?

rovelo is a domestic tire brand - Rovelo Tire, a brand under Sailun Jinyu Group Co., Ltd., officially launched in China in 2015. The company has modern tire manufacturing plants in Qingdao, Dongying, Shenyang in China and Tay Ninh in Vietnam, a natural rubber deep processing base in Thailand, and sales networks and logistics centers in Canada, the UK, and other regions serving the Americas and Europe. Here is more information about rovelo Rovelo Tire: 1. As a niche domestic brand, rovelo Rovelo Tire had already been sold in the European and American markets and received excellent market feedback before its domestic debut. Its products feature novel designs and outstanding performance, with low noise, low rolling resistance, and superior handling, which have been highly recognized by European and American consumers. As a new brand of Sailun Jinyu Group, its products have passed the certification of the European Tire Labeling Regulation. As a green tire, its entire production process reflects the concepts of environmental protection, safety, and people-oriented principles. 2. Rovelo Tire has low noise and good quality. It features small rolling resistance, high load capacity, excellent vibration damping, and strong handling and wear resistance. However, the price is relatively slightly higher, and the comfort is a bit less.

What brand is Triangle?

Triangle tires are produced by Triangle Group. Below are specific details about car tire replacement: 1. Replacement time varies depending on conditions: For drivers with good driving habits, tires generally need to be replaced every 3-5 years or after traveling 60,000-80,000 kilometers. If driving conditions are harsh, such as frequently traveling on gravel roads or experiencing frequent traffic jams, sudden braking, or sharp turns, the replacement interval will be shorter. 2. Tire aging time: The main material of tires is rubber, which naturally ages over time. Signs of aging include hardening of the tire and small cracks appearing on the sidewalls. Typically, natural aging occurs within 4-5 years. Tires should be replaced after 5 years to prevent the risk of blowouts. 3. Observe tire wear: If the tire is severely worn and the tread pattern is level with the wear indicator, the tire should be replaced. Otherwise, braking on wet or slippery roads will be more difficult, increasing the risk of losing control of the vehicle. Driving on rough roads with severely worn tires also increases the risk of blowouts.

What Causes the Battery Warning Light to Illuminate?

Reasons for the battery warning light illumination: 1. Loose battery terminals or battery cable connections. 2. Battery not holding charge. 3. Alternator not generating electricity. 4. Alternator malfunction, such as regulator failure. 5. Fuse and relay faults. Relevant information about automotive batteries is as follows: 1. Proper electrolyte level maintenance: The electrolyte level should always be maintained between max and min marks, checked monthly. Add distilled water (pure water) as needed when the level drops, but never add acid. 2. Timely recharging: When the battery voltage is insufficient, with dim lights and weak starting power, perform external charging promptly. Avoid overcharging or prolonged undercharging, as overcharging can cause active material shedding while undercharging leads to plate sulfation. Ensure the regulator voltage remains neither too high nor too low.

How Many Kilometers Should Car Tires Be Replaced?

Car tire replacement mileage should be determined based on various factors such as tire quality, driving conditions, and driving style. Generally, it is optimal to replace tires around 60,000 to 80,000 kilometers. However, tire replacement should not solely depend on mileage; the service life of the tires should also be considered, requiring a combined judgment. Relevant information about tires is as follows: 1. Tires are consumables: Tires are rubber products, and rubber naturally ages after a certain period of use. Typically, tires will show signs of aging after about 4-5 years of use. 2. How to check the production date of tires: The production date of tires is indicated by a 4-digit number on the sidewall of the tire. The first two digits represent the week, and the last two digits represent the year of production.
