The reasons why the fuel pump automatically shuts off when refueling are: 1. High temperature causes increased air pressure inside the fuel tank, leading to the automatic shut-off of the fuel pump; 2. Fast refueling speed causes fuel splashing, resulting in the pump shutting off; 3. The fuel tank's pipe structure is too convoluted, causing fuel spray and pump shut-off. The fuel tank is the heart of a fuel-powered vehicle. Without it, the vehicle would be rendered useless. The fuel tank stores fuel and serves to dissipate heat, as well as separate bubbles and impurities from the fuel. Due to the auxiliary components installed inside, fuel tank maintenance is an essential part that car owners should not overlook. The fuel tank is designed on the right side to maintain the vehicle's front-rear balance, ensuring safer vehicle structure on complex and uneven roads.

Are the engines of Toyota 86 and Subaru BRZ the same?

Subaru BRZ and Toyota 86 share the same engine, both utilizing the FA20 horizontally opposed naturally aspirated four-cylinder engine. Here are the detailed specifications of the FA20 engine: 1. The FA20 engine delivers a maximum power output of 147 kW and a peak torque of 205 Nm. Its maximum torque is achieved between 6,400 to 6,600 rpm, while the maximum power is reached at 7,000 rpm. 2. The FA20 engine incorporates Toyota's D-4S dual injection technology. This hybrid fuel injection system allows the engine to switch between different fuel injection modes based on operating conditions, enhancing both efficiency and performance. 3. The horizontally opposed design of the engine results in a low center of gravity. The use of the FA20 engine lowers the vehicle's overall center of gravity, thereby improving handling characteristics. 4. The FA20 engine is paired with either a 6-speed manual transmission or a 6-speed automatic transmission.
