Week 10 (May 30)

We had finished our stage 2 presentation yesterday. Gerry did not believed vacuum pump i founded suitable for use in our project. So i need to research more information and suitable vacuum pump to install in our vehicle.

HELLAs Electric Vacuum Pump ensures consistent and effective brake power. Until recently, the majority of vehicle brake boosters used the vacuum generated from the manifold of the internal combustion engine. However, with today’s advanced engine technologies (i.e. downsizing) or under certain operating conditions (i.e. cold start/engine warm-up phase), the vacuum provided by the engine is no longer sufficient. Furthermore, advanced engine technologies, such as electric or hybrid vehicles, are not capable of generating any vacuum pressure. HELLAs electric vacuum pump provides alternative or additional vacuum for these advancements in technology. Advantages → Reduced energy loss with “switch on-demand” → Reduction of emissions and CO2 → No mechanical interface required → Maintenance free → Supports a flexible vehicle platform design HELLA delivers three different types of electric vacuum pumps (UP28, UP30, UP 32). They can be distinguished by their respective performance and by the size of the vehicle braking system.
