What are the differences between Swift 1.3 and 1.5?

What are the common engine sensors?

There are 6 common engine sensors. Here are the detailed introductions: 1. Crankshaft Position Sensor: The crankshaft position sensor is used to detect engine speed and provide crankshaft rotation angle. It is installed near the flywheel. 2. Coolant Temperature Sensor: Used to detect the temperature of the cooling system to ensure the engine operates at an appropriate temperature. It is installed on the engine water passage. 3. Intake Air Temperature Sensor: Used to detect the temperature of air entering the engine, mainly to adjust fuel injection volume. When the external temperature is too low, it increases fuel injection; when too high, it reduces fuel injection. It is installed on the intake bellows. 4. Intake Pressure Sensor: Used to determine the fuel injection pulse width and ignition advance angle of the engine. It is generally installed on the intake manifold. 5. Camshaft Position Sensor: Also known as the phase sensor, it is installed near the camshaft. 6. Oxygen Sensor: To control vehicle emissions, the ECU monitors the concentration of exhaust gases to adjust fuel injection, bringing the actual air-fuel ratio closer to the theoretical air-fuel ratio. The oxygen sensor serves this function and is usually installed on the exhaust manifold.

What are the sidewall markings on Pirelli tires?

Pirelli's run-flat tires are marked with R-F or EUFORI. This means that if you see R-F or EUFORI markings on the sidewall of a tire, it indicates that the tire is a Pirelli run-flat. Here is some related information: EUFORI: EUFORI is a unique MIRS tire produced by Pirelli, representing Pirelli's innovative run-flat technology. Each brand has different markings for run-flat tires. Goodyear's run-flat tires are marked with ROF; Bridgestone's run-flat tires are marked with RFT; Dunlop's run-flat tires are marked with ROF or DSST; Dema brand run-flat tires are marked with SSR; Michelin's run-flat tires are marked with ZP. Additionally, some brands may have a five-pointed star on the sidewall to indicate run-flat tires. Important Notes: It is important to note that the primary purpose of run-flat tires is not to drive long distances after a puncture, but to maintain vehicle stability and prevent accidents. Therefore, even when using run-flat tires, it is essential to replace the tire as soon as possible after a puncture and avoid prolonged driving.

What is the Depreciation of a Car After Body Repair and Painting?

Generally, if a car has been in a major accident where the frame or main pillars were damaged and repaired, the depreciation can range from 10% to 30%. For minor body repairs and painting, there is usually little to no depreciation. Introduction to Auto Body Repair: Auto body repair refers to the process where there is visible deformation in the car. Based on the extent of the deformation, repair technicians use methods such as cutting, stretching, or grinding to correct the car's body. Then, they apply putty to reshape the body, restoring the damaged part as closely as possible to its original condition. A car is mainly composed of structural components and outer panels. Structural components primarily include the four beams and six pillars, and damage to these areas usually results from significant accidents or collisions. Generally, most modern cars use aluminum alloy bodies, which require specialized aluminum powder and curing powder for filling and repair. However, these materials are relatively costly. To save costs, many repair shops may use ordinary putty powder for filling. Although the visual appearance may be the same after painting, the performance may degrade over time, and the repaired area could deform again.

What does SAE on engine oil mean?

SAE on engine oil stands for the abbreviation of the Society of Automotive Engineers, and the SAE grade represents the viscosity grade of the oil. Here are some relevant details about engine oil: 1. Types of engine oil: Engine oil refers to lubricants specifically used in internal combustion engines. In addition to lubrication, it also has functions such as cleaning, rust prevention, and cooling. 2. Composition of engine oil: The base oil of currently used engine oil is composed of hydrocarbons, poly-alpha-olefins (PAO), and poly-internal-olefins (PIO), all of which are organic compounds consisting solely of carbon and hydrogen. Some high-grade engine oils may contain up to 20% esters. 3. How to use engine oil: There are many types of engine oil available on the market. It is best not to mix two different brands of engine oil, as the additives used in different brands may vary, and mixing them could cause the oil to deteriorate. If mixing is necessary, a compatibility test should be conducted first. If the oils are compatible, they can be mixed, but the quality of the new oil will significantly decrease. 4. How to choose engine oil: It is generally difficult to distinguish the quality of engine oil based on appearance alone. Therefore, when purchasing engine oil, it is advisable to choose well-known brands of lubricants and buy from authorized dealers of reputable brands. The quality can be determined based on the API oil quality grade, and the packaging should clearly display the manufacturer's address, production date, and batch number.

What Causes Backfiring in a Car's Exhaust Pipe?

Backfiring in a car's exhaust pipe can occur due to the following reasons: 1. Overly rich or lean air-fuel mixture: When the engine's combustible mixture is too rich, incomplete combustion occurs, and unburned mixture enters the exhaust pipe. Upon encountering fresh air in the exhaust system, it reignites, causing an explosion sound. Conversely, if the mixture is too lean, the spark energy may be insufficient to ignite it, leading to combustion in the exhaust pipe and resulting in backfiring. 2. Excessive fuel level in the float chamber: This creates an overly rich mixture and allows some fuel to enter the cylinder without proper atomization. The unburned fuel then travels to the muffler, where it reignites, causing backfiring. 3. Excessive ignition advance angle or excessive valve overlap: Incorrect gear installation can cause the exhaust valve to open prematurely, leading to backfiring. 4. Weak or interrupted spark: If the combustible mixture fails to ignite during a stroke, it may be ignited by high-temperature gases from the next stroke after entering the muffler. 5. Excessive fuel during startup: Multiple starting attempts can create an overly rich mixture, accumulating fuel in the cylinder and causing oil droplets to exit the muffler. When the engine starts, the fuel in the muffler ignites, resulting in backfiring. 6. Faulty ignition coil: A damp or leaking ignition coil can cause unstable or interrupted sparking, leading to backfiring, even if the CDI, high-voltage coil, and spark plug are functioning properly.

How to Use a Column Shifter?

When shifting gears, press the brake pedal and then move the gear lever, just like with a regular automatic transmission car. After starting, the gear is in neutral (N). Pushing the lever upward engages reverse (R), while pushing it downward engages drive (D). When parking, press the brake, shift to neutral (N), then press the external button to engage park (P). Below is relevant information about column shifters: 1. One button on the column shifter is for park (P). Gently pushing the lever forward or backward engages neutral (N), pushing it firmly forward engages reverse (R), and pushing it firmly backward engages drive (D). The parking brake is replaced by the park (P) position. Remember to press the brake when shifting. 2. The term "column shifter" comes from the motion of pulling the gear lever toward the driver's chest when shifting. There are two types of gear lever arrangements in cars: floor-mounted and column-mounted. A gear lever located below the right side of the steering wheel is called a column shifter, which is more common in American cars. 3. Column shifters are generally automatic. Currently, common American cars with column shifters in the Chinese market include the Buick GL8 and older Regal models. German brands like Mercedes-Benz also frequently use column shifters, such as in the C, E, R, S, ML, and GL series. British brand Rolls-Royce's three current models (Phantom, Ghost, Wraith) also feature column shifters.
