Q how does a four cycle engine work

A four-cycle engine, also known as a four-stroke engine, works through a process of four specific phases: intake, compression, combustion/power, and exhaust. These phases occur in a cycle that repeats itself, driving the movement of the vehicle. 1. Intake Stroke: The cycle begins with the intake stroke in which the piston moves down the engine cylinder while the intake valve opens. This creates a partial vacuum that sucks in a mixture of air and fuel. 2. Compression Stroke: The intake valve closes, and the piston moves back up the engine, compressing the air-fuel mixture. Near the top of this stroke, the spark plug fires creating a tiny, controlled explosion that forces the piston to move down, driving the power stroke. 3. Power/Combustion Stroke: The ignited fuel-air mixture burns rapidly, greatly increasing the pressure within the engine and causes the piston to descend down the cylinder. This translates to a force on the connecting rod connected to the crankshaft and therefore gener...

Q how to move an engine without a hoist

Moving an engine without a hoist can be quite challenging due to their weight and size. Here’s a simple guide to help you out: 1. Assemble the necessary tools: Before anything else, you will need strong chains or straps, a hydraulic jack, a storage crate or anything that can support the weight of the engine. 2. Disconnect Everything: Start by disconnecting all cables, hoses, lines, wiring, and attachments that are connected to the engine like the transmission and exhaust. Also remove the engine mount bolts. 3. Secure Engine: Wrap your chain or strap around the engine and make sure it is secured. If the engine has lifting points, use them. 4. Using Jack: Slide your hydraulic jack underneath the engine. Pump the jack until it is taking most of the weight of the engine. If your car is up on blocks or stands, you should be able to take the full weight of the engine on the jack. 5. Slide out the Engine: Lower the jack slowly. Once the engine is free, you and a helper (if you have one)...

Q how to measure engine rpm without a tachometer

There are two effective methods for measuring engine RPM without a tachometer. The first involves using an app that analyzes sound frequencies to approximate RPM. By utilizing the smartphone’s microphone. this app can detect engine sounds and calculate the RPM based on the noise pattern. Another practical approach is using reflective tape and a laser tachometer. This method involves applying reflective tape to the rotating parts of the engine and then using a handheld laser tachometer to measure the RPM by pointing it at the tape. The device sends a laser beam that reflects off the tape and calculates the RPM based on the frequency of the reflected signal. Both options offer solutions when a traditional tachometer is not available. but they may require calibration and verification of source accuracy based on a known RPM.

1. For accurate readings. it is recommended to conduct tests while driving rather than starting the vehicle. 2. Locate your car’s OBD-II port. which can usually be found under the driver’s side dashboard. If you are unable to find it. consult your vehicle’s manual for assistance. Connection with OBD-II Scanner: Simply connect the scanner directly to the port. Once connected. start the vehicle. 4. The majority of scanners will initiate scanning automatically; however. if yours does not. look for a Scan button or similar option on the scanner itself. Code Check: The scanner will reveal a code that corresponds to the issue detected in your car. While this code is only a starting point and does not provide specific details about the problem. you can refer to your scanner’s documentation for further explanation of each code’s meaning. Code Explanation: Each code is comprised of a combination of letters and numbers. with the first letter indicating which area of...
