Partial sterling combustion engine design

2008-08-28 18:29:38 by wuzawuzzal


The main idea is to have the cylinders charge and detonate fuel in an computer controlled automated way as to reduce the amount of combustion cycles that would other wise be necessary to keep the engine running.
The piston is directly connected to a pneumatic actuator that extends and retracts to either draw in fresh fuel or expel exhaust gases. A charge is loaded and valves are operated pneumatically to open a path to the drive train or to exhaust spent fuel. A pressure relief valve is installed to prevent over pressure and also to direct excess cylinder pressure to a pressure tank (not shown) to be used to power actuators

Keltron receives order worth Rs 2.44 crore  — The New Indian Express
The pneumatic actuators will be manufactured at the Keltron Controls division of Keltron at Aroor in Alappuzha district.

Semiconductor Processing Improves with FPGA-based Controller  — Automation World
The machine includes a rotary mechanism with pneumatic actuators to handle freshly diced wafers, which are identified by a gigabit Ethernet camera to position the stage to pick components of the freshly cut silicon with actuators.
