Fuel delivery modules
Delivery modules supply fuel to gasoline or diesel injection systems and nowadays are completed integrated into a vehicle´s fuel tank. Because they take up very little room, Bosch fuel delivery modules are suited to all common fuel tank types. What is more, they are lightweight, while the high efficiency of their delivery pumps helps to reduce CO2 emissions.

Yachiyo fuel tank
The fuel tank is one of the parts that stores automobile gasoline and light oil. Fuel is necessary for automobiles, but also a dangerous highly flammable material. Therefore, the fuel tank is positioned as an important maintenance part and Yachiyo develops it with consideration for the customer’s safety not only in the case of an automobile collision, but also during normal use, to ensure against fuel leakage.
Generally, the fuel tank is mainly made of a steel sheet, but recently plastic is used in order to make the vehicle lighter. Yachiyo prepares for the production system for both steel and plastic, depending on the customer’s request for destination and the environmental regulations there.
With conventional wastegated turbochargers or fixed geometry turbochargers (FGT), a turbine flow area cannot be adjusted during operation.
Knocking is abnormal combustion in which the air-fuel mixture ignites prematurely due to exposure to high temperature and pressure, creating an unwanted high-frequency noise. When the compression ratio is increased, the temperature at compression top dead center (TDC) also rises, increasing the probability of knocking.
