What does dual engine mean in cars?

Dual engine in cars refers to HEV (Hybrid Electric Vehicle), also known as mild hybrid. Although dual engine models belong to hybrid vehicles, they are not classified as new energy vehicles and thus do not qualify for national new energy subsidies or other policy benefits, and must be registered with blue license plates. The characteristic of HEV is that it does not require charging, and its operation mode is the same as that of conventional fuel-powered vehicles. The battery capacity and motor power in dual engine vehicles are relatively small, serving only as an auxiliary to the engine. They participate in driving only during startup, low-speed conditions, or uphill sections, thereby reducing engine load and lowering fuel consumption. Dual engine cars do not produce any exhaust emissions, thus reducing smog pollution levels, and can charge the battery while driving, eliminating the need for charging via power cables.

I've been driving a hybrid car for several years, and I feel this thing is a fuel-saving marvel in the automotive world. Essentially, it combines a gasoline engine with an electric motor to work together. When driving in the city, it automatically switches to electric mode, unlike traditional cars that constantly burn fuel, cutting fuel consumption by half. This is especially noticeable during traffic jams, where it's as quiet as an electric vehicle but without the worry of running out of power since you can just refuel. In the long run, lower emissions are better for the air, and I save a significant amount on fuel costs each year, making it quite cost-effective. The downside? It's a bit more expensive initially, but it pays for itself in a few years. The mechanic mentioned the battery lasts about ten years, so durability is good. Overall, I chose it for environmental reasons and to save money, plus it significantly improves the driving experience, especially for city living.

As someone who loves delving into cars, let me tell you that the dual hybrid is essentially a hybrid power system, with its core consisting of two machines: a regular gasoline engine paired with a small electric motor. They work together intelligently—for example, in traffic jams or at low speeds, the pure electric mode kicks in, offering super quiet operation and fuel savings; during acceleration, both power sources combine forces; and when braking, energy is recovered and stored in the battery. The battery is typically nickel-metal hydride, requiring no plug-in charging—just refuel as usual, with fuel consumption dropping to around 4 liters per 100 kilometers. This design is truly ingenious, delivering high efficiency in my driving experience while avoiding the range anxiety of pure electric vehicles. Maintenance-wise, the battery comes with a long warranty, and routine upkeep is similar, posing no major hassles. It’s more eco-friendly and cost-effective in the long run, making a tech enthusiast like me particularly satisfied.

Are plug-in hybrids subject to traffic restrictions?

Plug-in hybrids are subject to traffic restrictions. Plug-in hybrid vehicles can use new energy license plates, but they do not enjoy the unrestricted driving policy. Only pure electric vehicles are exempt from traffic restrictions. The driving principle and driving unit of plug-in hybrid vehicles are the same as those of electric vehicles, with the only difference being that they are equipped with an engine. The battery of plug-in hybrid vehicles is quite large, allowing these vehicles to be charged via an external power source. Plug-in hybrid vehicles have a longer range in pure electric mode. The fuel consumption of plug-in hybrid vehicles is much lower than that of pure gasoline vehicles, and their range is also longer than that of most pure electric vehicles. Most plug-in hybrid vehicles generally use ternary lithium batteries.

What is the minimum ground clearance of the Volkswagen Jetta?

The minimum ground clearance of the Volkswagen Jetta is 120mm. Ground clearance, also known as minimum ground clearance, refers to the smallest distance between the car's chassis and the ground when the vehicle is at maximum load. The minimum ground clearance reflects the car's ability to pass over obstacles or uneven surfaces without collision. The Jetta is a car brand under FAW-Volkswagen Automotive Co., Ltd., a joint venture of the German Volkswagen Group in China. The new Jetta includes 9 models with three engine displacements: 1.4L, 1.5L, and 1.4TSI, paired with 5-speed manual, 6-speed automatic, and 7-speed dual-clutch transmissions, equipped with Volkswagen's new-generation EA211 series engines.

Where is the transmission fluid filler port located?

The transmission fluid filler port is located on the transmission oil pan. There is a yellow ring at the upper left corner of the engine. Below the yellow ring is a nut. By gripping and unscrewing this ring, you can add transmission fluid. Transmission fluid replacement interval: The replacement interval is generally two years or 40,000-60,000 kilometers. During normal operation, transmission fluid operates at temperatures around 120 degrees Celsius, requiring high-quality fluid that must remain clean. It's difficult to determine whether the fluid needs replacement through visual inspection or touch alone. However, after prolonged use, the fluid accumulates significant impurities. If not replaced promptly, these impurities can wear down the engine over time, shortening the vehicle's lifespan. Transmission fluid replacement method: The preferred method is dynamic fluid replacement using specialized transmission cleaning equipment. During transmission operation, the old fluid is thoroughly circulated and completely drained before adding new transmission fluid. This achieves a replacement rate of over 90%, ensuring effective fluid renewal. Function of transmission fluid: Transmission fluid maintains cleanliness in the gear system, lubricates to prolong the lifespan of transmission components, provides effective lubrication even in low-temperature conditions, and reduces fluid loss under harsh operating conditions. Depending on transmission type, transmission fluid is categorized into automatic transmission fluid (ATF) and manual transmission fluid.

Can plug-in hybrids get green license plates?

Plug-in hybrids can get green license plates. Green license plates are new energy vehicle license plates, and both pure electric vehicles and plug-in hybrid vehicles can generally use green new energy license plates. Plug-in hybrid vehicles are different from ordinary hybrid vehicles. Ordinary hybrid vehicles cannot use an external power source to charge the vehicle's battery, and their range in pure electric mode is relatively low. Plug-in hybrid vehicles have a significantly larger battery, allowing them to be charged via an external power source, and they offer a longer range in pure electric mode. Plug-in hybrid vehicles consume much less fuel than pure gasoline vehicles and also have a longer range compared to most pure electric vehicles.
