Lavida Plus: Should I Use 92 or 95 Octane Gasoline?

According to the official vehicle manual recommendation, the Lavida Plus should use 92 octane gasoline. In addition to checking the suitable gasoline grade in the vehicle manual, you can also find it marked on the fuel tank cap of the Lavida Plus. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with a compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. However, with the application of new technologies, the compression ratio alone cannot determine the gasoline grade. High compression ratio engines can also be tuned to use lower octane gasoline because, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline octane number, the higher the octane value and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the Lavida Plus occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, prolonged use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane value will alter the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Due to the significantly lower octane value, the gasoline's ignition point decreases, causing premature ignition during the compression stroke. If combustion occurs before the spark plug ignites during the compression stroke, resistance will arise during the upward stroke. This resistance makes the engine run very unstably. If the knocking is imperceptible, it only increases noise without obvious engine damage. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

Standard Tire Pressure for Sedans?

The normal standard tire pressure for small cars is between 2.2-2.5 BAR. Here is an introduction about tire pressure: Normal range: The appropriate normal tire pressure is between 2.3~2.7 BAR. However, in summer when temperatures are high, the tire pressure may rise above 3.0 BAR after driving, so a tire pressure value between 2.3~2.5 BAR is more suitable in summer. Excessive tire pressure: This will reduce the friction and adhesion of the tires, affecting braking performance; cause steering wheel vibration and deviation, reducing driving comfort; accelerate wear on the central tread pattern of the tire, shortening tire lifespan; increase vehicle vibration, indirectly affecting the lifespan of other components; when encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, and the impact may cause internal cracks and explosions, leading to a blowout. Insufficient tire pressure: This will increase the friction coefficient with the road surface, raising fuel consumption; cause heavy steering and deviation, posing risks to driving safety; increase movement in various parts of the tire, leading to abnormal overheating due to excessive rolling; multiply the friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength, which may cause a blowout during high-speed driving; insufficient tire pressure will increase tire deformation, making the sidewalls prone to cracks and causing flexing movements, leading to excessive heat, rubber aging, fatigue in the cord layer, and cord breakage, while also increasing the tire's contact area with the ground, accelerating shoulder wear.

Who invented the rotary engine?

The inventor of the rotary engine is Felix Wankel from Germany. The rotary engine directly converts the combustion expansion force of flammable gas into driving torque. Compared with reciprocating engines, the rotary engine eliminates useless linear motion, so a rotary engine of the same power is smaller in size, lighter in weight, and has lower vibration and noise, giving it significant advantages. Due to the axial operation characteristics of the rotary engine, it can achieve higher operating speeds without requiring precise crankshaft balancing. The entire engine has only two rotating components, which is a significant simplification compared to the more than twenty moving parts, including intake and exhaust valves, found in a typical four-stroke engine. This also greatly reduces the possibility of malfunctions.
