4-stroke engine gives better mileage than a 2-stroke engine, and here’s why:

  4-stroke engine gives better mileage than a 2-stroke engine , and here’s why: Key Reasons 1️⃣ Efficiency of Combustion 4-stroke engines complete the intake, compression, power, and exhaust strokes in 4 piston movements . This allows more complete combustion of fuel , extracting more energy per unit of fuel. 2-stroke engines complete a cycle in 2 strokes , which can cause fuel loss during scavenging , making them less fuel-efficient. 2️⃣ Fuel Consumption 4-stroke engines burn less fuel for the same distance , so mileage is higher . 2-stroke engines inject fuel more frequently and some of it escapes unburned, reducing efficiency. 3️⃣ Lubrication 2-stroke engines mix oil with fuel, causing more energy loss and higher consumption . 4-stroke engines have a separate lubrication system , improving efficiency. 4️⃣ Durability and Maintenance 4-stroke engines run cooler and last longer, maintaining efficiency over time. 2-stroke engines wear fast...

The age of the Earth is approximately 4.54 billion years.

 The age of the Earth is approximately 4.54 billion years . 📌 How scientists know this This age is calculated using: Radiometric dating of the oldest Earth rocks Dating of meteorites (which formed at the same time as Earth) Evidence from lunar rocks brought back from the Moon All methods point to the same age: ➡️ 4.54 ± 0.05 billion years
