What is the engine RPM when a sedan reaches 120 km/h?

1 Answers

There is no fixed value for engine RPM when a car reaches 120km/h. The engine speed and influencing factors are as follows: Introduction to engine RPM: The level of engine RPM relates to the number of work cycles per unit time or the effective power output of the engine, meaning the engine's effective power varies with different RPMs. Therefore, when specifying the engine's effective power, the corresponding RPM must be indicated simultaneously. Factors influencing engine RPM: Besides being affected by fuel octane rating and anti-knock properties, automobile engine RPM is generally also related to factors such as engine material and manufacturing, high-voltage current magnitude, valve train condition, and lubricating oil quality.

Where is the fuse box located in the 12th-generation Crown?

Toyota Crown has two fuse boxes, one in the engine compartment and one in the cabin. Below is additional information: 1. Automotive Fuse Box: An automotive fuse box is used to install car fuses. Based on the size of the installed fuses, they can be categorized into: small automotive fuse boxes, medium automotive fuse boxes, and large automotive fuse boxes. When selecting an automotive fuse box, factors such as the current rating of the fuse and the size requirements should be considered, allowing for the choice of different fuse boxes. 2. Fuses: Fuses, officially known as 'circuit breakers,' serve a similar purpose in cars as they do in households—they melt when the circuit current is abnormal and exceeds their rated current, acting as a protective barrier for the circuit. Automotive fuses are broadly divided into two types: fast-acting fuses and slow-blow fuses. When replacing fuses in the Crown, ensure the appropriate fuse is selected.

Why is one side wider and the other narrower when reversing into a parking space?

The main reason for one side being wider and the other narrower when reversing into a parking space is the incorrect timing of steering wheel operation. Here are the relevant explanations: 1. Steering too early: When the steering wheel is turned too early during right-side reversing, the wheels will be closer to the corner of the parking space, resulting in a left-wide and right-narrow situation after parking. 2. Steering too late: When the steering wheel is turned too late, the parked vehicle will exhibit a left-narrow and right-wide condition after reversing into the space. 3. Reverse parking: Also known as reverse pole or pole test, this is an assessment point in driver's tests where the examinee must correctly reverse the vehicle into a garage space from both sides while in motion. It primarily evaluates the driver's ability to maneuver the vehicle in confined spaces and their spatial awareness during vehicle movement.

What is the total loss standard for water-damaged vehicles?

The following is an introduction to the total loss standards for water-damaged vehicles: 1. Level 1: The water has just reached the vehicle's chassis, and the exhaust pipe, fuel tank, and carbon canister may be submerged. The vehicle floor may become damp, but the likelihood of significant water ingress is low, and the impact on the vehicle's electrical equipment is minimal. 2. Level 2: The water level reaches halfway up the wheels. Due to the vehicle's incomplete sealing, water will begin to enter the interior. For lower-sitting sedans, the water level inside may affect the adjustment motors of the seats as well as electrical components such as heating and ventilation. 3. Level 3: The water almost completely submerges the tires. At this point, the water level inside the vehicle will fully immerse the seat cushions and the central armrest area, while also affecting a large number of electrical components.
