Refine S4's engine is independently developed by JAC Motors and produced in JAC's engine manufacturing plant. This vehicle is equipped with the following two engines: 1. The 1.5-liter turbocharged engine, codenamed HFC4GC2.4D, has a maximum power of 110 kW, a maximum torque of 210 Nm, a maximum power speed of 5500 rpm, and a maximum torque speed range of 2000 to 4500 rpm. This engine features i-VVT technology, uses multi-point fuel injection, and has an aluminum alloy cylinder head and block. It is paired with either a 6-speed manual transmission or a CVT transmission. 2. The 1.6-liter naturally aspirated engine, codenamed HFC4GB3-3D, has a maximum power of 88 kW, a maximum torque of 150 Nm, a maximum power speed of 6000 rpm, and a maximum torque speed range of 3500 to 4500 rpm. This engine features DVVT technology, uses multi-point fuel injection, and has an aluminum alloy cylinder head and block. It is paired with either a 6-speed manual transmission or a CVT transmission.

I often research domestic cars. The engine of the JAC Refine S4 is independently developed by JAC Motors, with the model number such as HFC4GB2.4D, which is a 1.5-liter turbocharged engine. It adopts advanced technologies like direct injection and an efficient combustion system, delivering strong power output with a fuel consumption of around 7 liters per 100 kilometers, making it quite economical. Compared to some joint-venture brands, this JAC engine has more advantages in terms of reliability and maintenance costs. I've driven it a few times, and it responds quickly to acceleration with well-controlled noise levels. As a representative of independent innovation, it complies with the China VI emission standards and has proven to be largely trouble-free over long-term use.

I've been driving the JAC Refine S4 for quite some time now, and the engine is JAC's own brand. What impressed me most is its durability and fuel efficiency. The model is something like HFC4GB2.4D, with a 1.5T displacement, providing ample power for daily driving without being fuel-thirsty. Compared to some imported models, it has lower maintenance costs, and parts are easy to find, making each service quite affordable. I think this kind of self-designed car is quite practical for city commuting—it starts quickly, accelerates smoothly at traffic lights, and is stable enough for long-distance trips.

The engine used in the JAC Refine S4 is from JAC Motors, such as the model HFC4GB2.4D. It features turbocharging, which enhances power efficiency and also saves fuel. It runs smoothly in daily driving, has a low failure rate, and is easy to maintain, making it suitable for family use. I have tested its performance, and it responds quickly with low noise.

Is a Four-Wheel Alignment Necessary When Rotating All Four Tires?

Rotating all four tires does not require a four-wheel alignment. As long as the chassis has not been impacted, there is no need for an alignment—only wheel balancing is necessary. The functions of wheel balancing include: 1. Enhancing driving comfort; 2. Reducing fuel consumption; 3. Extending tire lifespan; 4. Ensuring straight-line stability of the vehicle; 5. Reducing wear on chassis suspension components; 6. Improving driving safety. A four-wheel alignment involves adjusting the geometric angles of the tires, steering, suspension, and other components to ensure proper tire contact with the ground. The installation of the vehicle's four wheels, steering mechanism, and front and rear axles must maintain specific relative positions, which are set by the manufacturer as standard values. Adjusting and restoring these positions is what constitutes a four-wheel alignment.

What Type of Engine Oil is Suitable for the Mazda Atenza?

The Mazda Atenza can use the original fully synthetic engine oil with a viscosity of 0W-20. If you want to change the oil during later maintenance, you can choose international brands such as Shell, Mobil, or Castrol. It is recommended to use 5W-30 or 0W-30 engine oil. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, resulting in smoother cold starts for the car. The latter number represents the kinematic viscosity of the oil at 100°C. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in the Mazda Atenza is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan. Use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out. Use a special wrench to remove the oil filter. Apply some oil to the oil seal of the new oil filter and tighten it clockwise by hand. Add the new oil through the oil filler cap on the engine's valve cover, usually filling about three-quarters of the oil container. Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter. If there are leaks, repairs should be made. After stopping the engine, pull out the oil dipstick to check if the oil level is within the standard range.

How much engine oil does the new Mondeo require?

1.5T version of the Mondeo requires approximately 4 liters of engine oil, while the 2.0T version requires around 5.5 liters. The oil change interval and precautions are as follows: Oil change interval: Generally, the engine oil should be changed every 5,000 kilometers. It is recommended to use the original manufacturer's oil during changes, as it ensures compatibility and prevents potential issues later on. Precautions for oil change: Do not mix different brands or types of engine oil, as this can lead to impurities, clogging the oil system. This may cause symptoms such as poor acceleration, unstable engine idle, difficulty starting, and in severe cases, may affect the engine's lifespan.

What transmission is the DSG based on?

Developed based on manual transmission. DSG refers to the transmission model used by Volkswagen. Similar issues occurred with the previous generation of transmissions, where some models experienced the "death flash." If this malfunction occurs while driving, it poses a significant safety hazard. Some car owners have reported instances where the vehicle suddenly loses power during driving, especially during acceleration. Additional information: DSG stands for Direct-Shift Gearbox. Unlike conventional automatic transmissions, the DSG is developed based on manual transmission rather than automatic transmission. This is because the DSG transmission allows for both automatic and manual shifting while driving, with manual shifting offering faster response times compared to standard manual transmissions. With Volkswagen's transition to a new platform, significant efforts have been made in engine tuning, not only resolving issues like the death flash and oil consumption but also greatly improving engine power and shift speed.
