What Causes Engine Oil Leaks?

What Are the S and L Gears?

Here is the relevant introduction about the S and L gears: 1. L Gear: Never engage this gear during normal driving. When accelerating or decelerating during driving, the vehicle's gear remains in the low gear. Maintaining a low gear while accelerating uphill provides stronger power. When going downhill, the low gear can help slow down the vehicle. 2. S Gear: When the S gear is engaged, the engine speed increases, and the fuel injection volume changes. At the same time, the adjustable suspension comfort becomes stiffer, reducing body roll during turns and alleviating nose-diving when braking. The trade-off for these effects is increased fuel consumption due to higher engine speeds, but the vehicle's overall performance is enhanced.

What is the battery model for Venucia T90?

Venucia T90 uses a 46B24L battery model with 12V output voltage, which is a lead-acid battery primarily composed of lead and its oxides, featuring sulfuric acid solution as electrolyte, manufactured by VARTA. Here are the main reasons for battery damage: 1. Not turning off vehicle electronics before engine shutdown, causing excessive instantaneous current during restart that damages the battery. 2. Leaving headlights on after parking, resulting in complete battery drain. 3. Modifying car circuits leading to excessive power load on the battery.

How Many Cylinders Does the Focus Engine Have?

Focus is equipped with a 3-cylinder engine, with 4 valves per cylinder. The working principle of an automobile cylinder is to guide the piston to perform linear reciprocating motion within the cylinder. In the engine cylinder, air converts thermal energy into mechanical energy through expansion; in the compressor cylinder, gas is compressed by the piston to increase pressure, thereby providing a power source. Below is an introduction to the classification of cylinders: 1. Single-acting cylinder: Only one end has a piston rod. Air is supplied from one side of the piston to generate pressure, which pushes the piston to extend and produce thrust, and returns via spring or self-weight. 2. Double-acting cylinder: Air is alternately supplied from both sides of the piston, outputting force in one or two directions. 3. Diaphragm cylinder: Uses a diaphragm instead of a piston, outputting force in only one direction and resetting via spring. It has good sealing performance but a short stroke. 4. Impact cylinder: This is a new type of component. It converts the pressure energy of compressed gas into the kinetic energy of the piston's high-speed (10~20 meters/second) movement to perform work. The impact cylinder adds a middle cover with a nozzle and a drain port.

Is it necessary to rotate front and rear tires?

Tire rotation between front and rear positions is necessary as wear patterns differ between them. Regular tire rotation is important. Below are specific details: 1. Generally speaking, for front-wheel-drive vehicles, since the front tires bear most of the forces during load-bearing, acceleration, steering, and braking, they wear out faster than rear tires, with a wear ratio that can reach 2:1. 2. In routine maintenance, frequent tire rotation helps ensure even wear, thereby extending tire lifespan. If signs of premature or irregular wear are observed, the rotation frequency may be appropriately increased. After rotation, a four-wheel alignment is required because it ensures the vehicle's suspension system and steering system are in standard condition.
