Parking diesel heater R07 is generally caused by insufficient fuel or fuel line blockage. Basic principle of diesel heater: The basic principle of a diesel heater is that it is a small internal combustion engine that directly burns diesel to obtain heat, and then uses the machine's heat dissipation to warm the cab. The diesel heater is also known as an air heater as it heats the air in the cab. Working principle of diesel heater: The diesel pump draws diesel from the fuel tank and delivers it to the combustion chamber, where the mixed gas is ignited by the ignition plug and burns in the combustion chamber. The exhaust gas produced by burning diesel is discharged through the exhaust port (to the outside of the vehicle). The outer wall of the combustion chamber is made of aluminum alloy with heat dissipation fins for fast heat conduction. The fan directly blows air towards the combustion chamber to send out the hot air.

What level of maintenance does tire disassembly, inspection, and rotation belong to?

Tire disassembly, inspection, and rotation belong to secondary maintenance. Below is an introduction to tire rotation: 1. Tire rotation is a maintenance measure to extend the service life of the vehicle's tires. Its main purpose is to prevent uneven wear on the car tires over time, which could affect driving safety. 2. The primary reason for uneven tire wear is that tires are divided into front drive wheels and rear non-drive wheels, which bear different forces and thus experience different degrees of wear. Additionally, during braking, the car does not distribute the braking force as evenly as one might think. Generally, the front wheels play the main role in deceleration, so the front tires usually wear out more severely than the rear tires.

What are the disadvantages of stock cars?

The disadvantages of stock cars: 1. The electronic control module is prone to problems: Since the vehicle has been parked for a long time, the circuit boards and connectors of the car are prone to moisture and oxidation corrosion due to long-term power failure, and some components may experience short-circuit faults due to prolonged power failure. 2. Oxidation and deterioration of various vehicle fluids: When the vehicle is parked, various fluids are in a static state. Engine oil, brake fluid, power steering fluid, transmission fluid, and other fluids may oxidize and deteriorate. The car battery may also experience leakage during parking, shortening its lifespan. If the vehicle is parked in an open parking lot, the paint surface of the car may also suffer from oxidation and corrosion. 3. Deformation of tires and steel rims: During parking, the tires, being made of rubber, may age and shorten their lifespan. The car's rims and tie rods may also deform. Oil leakage from shock absorbers is also one of the disadvantages of stock cars.

Can the Subject 2 Test Be Cancelled One Day Before?

Yes. Here are the details: 1. Cancellation Time: If the applicant is unable to attend the test at the scheduled time for any reason, they must apply to cancel the appointment at least one day in advance. According to Article 43 of the 'Regulations on the Application and Use of Motor Vehicle Driving Licenses', if an applicant fails to attend the test at the scheduled time without prior cancellation, the test will be deemed as a failure. 2. Subject 2: Subject 2, also known as the small road test, is part of the motor vehicle driving license assessment. It refers to the field driving skills test. For small vehicles (C1/C2), the test includes five mandatory items: reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving through curves (commonly known as S-curves). Some regions may also include a sixth item: high-speed toll collection.

How Much Engine Oil Should Be Added for Car Maintenance?

For regular car maintenance, approximately 4 liters of engine oil should be added. The filling amount should be between the upper and lower marks on the oil dipstick. Engine oil is the lubricant used by the engine, composed of base oil and additives. With a density of about 0.91kg×10 cubic meters, it serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and act as a shock absorber, earning it the reputation as the 'blood' of a car. Here is an introduction to car maintenance: 1. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. 2. Car maintenance mainly includes the maintenance of the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. 3. The purpose of car maintenance is to keep the car clean, ensure normal technical conditions, eliminate hidden dangers to prevent failures, and slow down the deterioration process to extend the service life.

What are the techniques for entering a right curve in Subject 2?

Subject 2 curve driving test is relatively simple, which involves safely driving the vehicle out along the designated "S"-shaped road. Here are the detailed steps: 1. Pay attention to the front of the car: When entering the S-curve, pay attention to the position of the front of the car, try to keep the outer front wheel of the vehicle close to the right edge of the curve, and drive in 1st gear with half-clutch. Do not stop during the process. During the process, you should also observe the left and right rearview mirrors to keep the vehicle driving along the S-road. 2. Turning left: Drive the vehicle close to the right side. When the left front corner coincides with the right edge line, turn the steering wheel one circle to the left, and make slight adjustments to keep the left front corner and the right edge line basically aligned. Drive along the S-road to turn left, and the vehicle will not press or cross the line. After passing the left curve, prepare to turn right.

Should you release the handbrake or shift to first gear first when starting in Subject 2?

Shift to first gear before releasing the handbrake. Below is a detailed introduction about the Subject 2 test: 1. Subject 2: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment. It is the abbreviation for the field driving skill test. The test items for cars C1 and C2 include five mandatory tests: reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving through curves (commonly known as S-curves). Some regions also include a sixth item: high-speed toll card collection. 2. Teaching objectives: Master the basic driving operation essentials and possess the fundamental ability to control the vehicle; proficiently grasp the basic methods of field and road driving within the test area, and have the ability to reasonably use vehicle control components and correctly control the vehicle's spatial position, accurately controlling the vehicle's driving position, speed, and route.
