The horizontally opposed structure is relatively complex, and there are issues such as oil lubrication that are difficult to resolve. Due to gravity, the horizontally positioned cylinders cause oil to flow to the bottom, leaving one side of the cylinders inadequately lubricated. The high-precision manufacturing requirements also lead to higher maintenance costs. Additionally, the wider engine body makes it less favorable for layout. Introduction to automotive engines: 1. The automotive engine is the device that provides power to the vehicle, serving as the heart of the car and determining its power, fuel efficiency, stability, and environmental friendliness. 2. Depending on the power source, automotive engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines, among others.

How often should the spark plugs be replaced on a Cadillac CT5?

The replacement interval for spark plugs on a Cadillac CT5 is 60,000 kilometers, with the original equipment using Ngkiltr6M9G spark plugs. Commonly known as spark plugs, their function is to discharge the pulsed high-voltage electricity delivered by the high-voltage wire, breaking down the air between the two electrodes of the spark plug to generate an electric spark, thereby igniting the air-fuel mixture in the cylinder. The spark plugs, in conjunction with the ignition system and fuel supply system, enable the engine to perform work, collectively determining the engine's performance to a large extent. The Cadillac CT5 is a luxury SUV under the Cadillac brand, featuring a four-door, five-seat configuration. In terms of powertrain, it is equipped with a 2.0T engine paired with a 10-speed automatic transmission. Exterior-wise, the Cadillac CT5 adopts the brand's signature design language, retaining the iconic lighting clusters, ensuring high recognition whether viewed from the front or rear.

How to Set Up a Car Alarm to Trigger Upon Touch?

To set up a car alarm that triggers upon touch, you need to install an alarm system for the vehicle and adjust its sensitivity to the highest level. Below are the specific steps to adjust the sensitivity of the car alarm: 1. Unlock the car and enter the vehicle, then press and hold the unlock button on the key for 5 seconds until the turn signals stay lit. 2. The vehicle will enter the alarm sensitivity setting mode. Without pressing the brake pedal, press the engine start button. 3. There are five levels of sensitivity in total, with level one being the lowest and level five the highest. Each press of the start button increases the sensitivity by one level. 4. It is generally not recommended to set the sensitivity to the highest level, as this may cause the alarm to trigger too easily. Usually, setting it to level three or four is more appropriate.

Is Brake Disc Rust a Serious Issue?

Brake disc rust is not a serious issue and is a normal phenomenon. The rust on brake discs is mainly caused by the vehicle being parked for extended periods, excessively humid air, or rain and snow. When parking the vehicle, it is advisable to choose a covered or relatively dry location to some extent avoid rust. Simply put, a brake disc is a round disc that rotates as the vehicle moves. The brake caliper clamps the brake disc to generate braking force, slowing down or stopping the vehicle when the brakes are applied. The method for replacing a brake disc is as follows: 1. Open the engine compartment and check the brake fluid level to prevent overflow during replacement; 2. Remove the wheel where the brake is located and the bolts of the brake caliper; 3. Take off the old brake disc, install the new one, tighten the guide bolts, and complete the replacement.

What is the Principle of Air Suspension?

Here is how air suspension works: 1. It utilizes an air compressor to generate compressed air, which is then used to adjust the vehicle's ground clearance; 2. Vehicles equipped with air springs generally have ground clearance sensors near the front and rear wheels. Based on the output signals from these sensors, the onboard computer detects changes in vehicle height and controls the air compressor and exhaust valves accordingly, causing the springs to automatically compress or extend to achieve a damping effect; 3. Air suspension also enhances the vehicle's adaptability. At high speeds, it can automatically stiffen to improve stability, while during prolonged low-speed driving on uneven roads, the onboard computer softens the suspension to enhance comfort; 4. Air suspension is not a recent technological development. The fundamental design is similar across systems, primarily consisting of an air spring filled with compressed air and a shock absorber with variable damping.
