Not : This story was written by someone who stayed at home because of Covit19. (I am not sick, there is a curfew.) Hypermile starts with car selection first. The market of dead cheap manual gasoline cars was my primary goal. This is how we met the Hyundai i10 1.0 petrol manual. I liked the car very much, I repeatedly examined it in showrooms. I took my wife and showed her. He liked his shape and size. I bought the 2014 model Hyundai i10 1.0 Bi-fuel Manual. She was 2 years old in mid-May 2016. . Thus, our Hypermile project comes to life. I fit in the front seats of the car very comfortably. My volumetric expectation was more than met. I bought a stroller, especially for luggage. I had plenty of room for my wife and daughter. I could use the front passenger seat as luggage. There is more than enough volume to meet all the needs of a family of three. The vehicle's aerodynamic coefficient is 0.31 cd. Small frontal area reduces friction. When you drive at a constant speed, your small engine doesn't stress about splitting the air. It is possible to use gravity in the most ideal way in ramp landings. You can glide at a speed of 85 km per hour in 5-% 6% inclines. While doing this, you can keep your vehicle in 5th gear. You won't lose speed. Your engine is very small, the number of friction parts is very low. It has 4 valves per cylinder, 3 cylinders, double overhead eccentric and variable timing. We have 90 Newton torque at 3500 rpm. Manual Transmission to increase efficiency As we transmit the power from the vehicle's engine to the ground, we lose a certain amount of power. A certain part of the power is lost in the transmission organs such as flywheel, gear, shaft, axle. A front-wheel drive car is the most ideal. Having Rwd will decrease efficiency. The differential of the direct transmission of the front-wheel drive vehicle will transfer power from there to the axles and provide traction to our tires with minimal loss. Torque converter in automatic transmission causes 30% to 35% power loss. In conventional gearboxes with spur gear or helical gear structure, the loss varies between 0.2% and 3%, while in solar gear structures this ratio varies between 2% and 10%. Locked clutch (clutch damper) mounted on transmissions with torque converter reduces the ratio of 9% This type of parts increases the number of moving parts, provides comfort and creates cost in maintenance. In any case, 25% of the torque received on the engine will be lost. The efficiency of the manual gearbox with light flywheel and light clutch lining can exceed 95%. Manual transmissions do not have an oil pump and do not need cooling. The losses are very low, as the internal gears lubricate with splashing oil. The loss in a small transmission, such as the i10 transmission, does not exceed 4% to 5%. If we do not count the loss caused by the torque converter, the loss in a standard automatic transmission working with the earth and sun gears is 13%. Likewise, if we do not count the loss of clutch during clutch, the loss in the classic manual transmission was measured as 4%. The Hyundai i10 is pretty good at this point in terms of efficiency. The transmission is directly connected to the engine. The transmission output is connected to the transaxle differential. The power of the engine is given to the front wheels without shortest. The loss here will be extremely small.
