Does the Highlander Have a Particulate Filter?

The Highlander does not come with a particulate filter across all its models. There are currently 9 available Highlander models on sale, none of which are equipped with a particulate filter, yet they still comply with the China VI emission standards. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, designed to capture particulate emissions before they are released into the atmosphere. It can reduce the soot produced by diesel engines by more than 90%, and the captured particulate matter is subsequently burned off during vehicle operation. How the particulate filter works: The diesel particulate filter is coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the particulate filter through a dedicated pipe. Inside, a densely arranged bag-type filter captures the carbon particles on a metal fiber felt filter. When the accumulation of particles reaches a certain level, a burner at the end automatically ignites, burning off the captured carbon particles and converting them into harmless carbon dioxide that is then released. To check if a Highlander has a particulate filter, you can use the following three methods: 1. Check the and to see if there is a particulate filter function. Additionally, carefully review the fault codes in the manual to see if there is a "particulate filter" warning light indicator. 2. Look at the label on the oil filler cap. If the cap clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. 3. Inspect the exhaust pipe behind the three-way catalytic converter to see if there is an additional cylindrical section. If present, that is the particulate filter.

What is Four-Wheel Alignment?

Four-wheel alignment is based on the four-wheel parameters of the vehicle, adjusted to ensure good driving performance and certain reliability. The installation of the steering wheels, steering knuckles, and front axle of a car has a specific relative position, which is called steering wheel alignment, also known as front-wheel alignment. Front-wheel alignment includes four aspects: caster angle, kingpin inclination angle, camber angle, and toe-in. Rear-wheel alignment includes camber angle and individual rear-wheel toe-in. Collectively, this is referred to as four-wheel alignment. Its purpose is to maintain stable straight-line driving, facilitate easy steering, and reduce wear on tires and steering components during driving. Below are relevant details: Functions: Front-wheel alignment includes caster angle, kingpin inclination angle, camber angle, and toe-in. Rear-wheel alignment includes camber angle and individual rear-wheel toe-in. Together, front-wheel and rear-wheel alignment are called wheel alignment, commonly known as four-wheel alignment. The role of wheel alignment is to keep the car driving straight stably, make steering easier, and reduce wear on tires and steering components during driving. Caster Angle: Viewed from the side, the steering kingpin (the rotation center when the wheel turns) tilts backward, which is called the caster angle. After setting the caster angle, a distance is created between the contact point of the kingpin centerline and the ground projection point of the wheel center (called the caster trail, similar to the backward tilt of a bicycle's front fork). This positions the wheel's contact point at the rear end of the kingpin's extension line, pulling the wheel backward due to rolling resistance during driving, naturally aligning the wheel with the driving direction. A large caster angle improves straight-line driving performance but also increases the caster trail. An excessively large caster trail can make the steering wheel heavy and worsen the wheel's bouncing due to road disturbances.

Does a Newly Purchased Car Need Antifreeze in Winter?

Newly purchased cars do not require additional antifreeze for winter. This is because new vehicles come with factory-installed antifreeze, which typically only needs replacement every two years or every 30,000 kilometers. The antifreeze replacement procedure is as follows: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with particular attention to the five-way water pipe. Antifreeze is distributed to different parts of the car through this five-way pipe to perform its function. If there is any antifreeze leakage in this section, replace the water pipe or resecure the connection as needed. Drain the old antifreeze, then flush the liquid channels with clean water. Add clean water to the antifreeze reservoir, then continue adding water to the reservoir so that it continuously flows through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir will have a faint pink color. Continue adding clean water until the outflowing water is clear. Note: Remember to remove the heater hose and drain all water from the heater core. Approximately one hour after draining, add new antifreeze through the radiator hose. Then, add another container of antifreeze to the antifreeze reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. During this time, the coolant level will drop slightly as air is expelled from the cooling system. Top up the antifreeze until it reaches the "MAX" mark on the reservoir.

Can Seat Heating Be Installed Aftermarket?

Seat heating can be installed aftermarket. Additional information about seat heating is as follows: 1. The seat heating function utilizes electric heating wires inside the seat to warm the interior, transferring heat to the occupant through thermal conduction. This improves comfort in winter when seats become uncomfortably cold after prolonged parking. 2. Seat heating products differ from other car seat cushions. Their performance and stability directly affect vehicle safety. If the heating pad quality is substandard, continuous high-temperature heating can easily cause the cushion to spontaneously combust, leading to fire hazards. 3. Uneven wiring or improper installation of heating pads can also result in spontaneous combustion incidents.

What does the anti-knock property of automotive gasoline mean?

The anti-knock property of automotive gasoline refers to the ability of gasoline to resist abnormal combustion (knocking) in the engine cylinders. Therefore, additives are mixed into gasoline to enhance its anti-knock properties. Additional information about gasoline anti-knock properties is as follows: 1. Strong anti-knock properties allow the use of higher compression ratio engines, which can improve engine power, reduce fuel consumption, and enhance the engine's economic efficiency. 2. To improve gasoline's anti-knock properties, tetraethyl lead additives are typically added to gasoline. Since tetraethyl lead is toxic, gasoline containing it is often dyed red for distinction to prevent misuse and poisoning.
