To determine if you have a Partial Zero Emissions Vehicle (PZEV) engine, first, look for a badge or sticker on your vehicle. Manufacturers often mark PZEV vehicles distinctly, usually on the rear or near the fuel filler cap. If no external markings are visible, the next step is to check your vehicle’s documentation, such as the owner’s manual or the emissions information sticker located under the hood or on the door frame. These documents typically list the vehicle’s emissions rating and engine type. PZEV engines are designed to produce significantly fewer emissions than standard gasoline engines, meeting strict standards set by the California Air Resources Board (CARB) and adopted by other states. Additionally, vehicle identification number (VIN) databases or contacting a dealership with your VIN can also confirm if your engine is PZEV certified. PZEV engines feature advanced emissions-reducing technology, making them an eco-friendlier option. Identifying whether you...

1. Intake: The intake valve opens, and as the piston goes down, a mixture of air and fuel is drawn into the cylinder. 2. Compression: Then the intake valve closes and the piston starts moving back up to compress the fuel mixture, making it highly volatile. 3. Ignition: Just before the piston reaches the top of its stroke, the spark plug ignites the fuel mixture. This causes an explosion which pushes the piston back down. 4. Exhaust: After the explosion, when the piston reaches to the bottom, the exhaust valve opens. As the piston moves back up it pushes out the exhaust gasses. After this, the exhaust valve closes, the intake valve opens, and the whole process starts over again. These four stages together are known as a Four-Stroke Cycle. Usually an engine has several cylinders (commonly four, six or eight) which are all doing these stages at slightly different times so that the explosions can be balanced out to keep the engine smoothly turning the crankshaft. The engine is more than ju...

An airplane engine works on the principles of basic physics: thrust and lift. The engines, typically powered by jet fuel, cause air to rush backwards out of the engine. According to Newton’s third law, “for every action, there is an equal and opposite reaction,” this force of air rushing backward creates an equal force pushing the aircraft forward – this is thrust. There are two main types of engines used in aircraft today: piston engines and jet engines. Both work on the same principles but have different designs. 1. Piston Engines: These engines are typically used on smaller, personal aircraft. The engine uses cylinders to draw in air and fuel, compresses it and then ignites it. The ignition pushes the piston back, driving the crankshaft which is linked to the propellers. This rotary motion of the propellers provides the necessary thrust. 2. Jet Engines: Jet engines, used on most commercial airlines, work by sucking in a large amount of air via a fan at the fr...
