brake release
5.For a specific brake mean effective pressure(BMEP),the maximum cylinder gas pressure,the maximum rate of pressure rise and the maximum rate of heat release increase with the increase of DMC addition at the middle and high loads while they remains less variation with DMC addition at the small load.
6.The results show that adjusting the proportions of DME and CNG is an effective technique for controlling HCCI combustion and extending the HCCI operating range. The maximum brake mean effective pressure (BMEP) for DME/CNG dual fueled HCCI operation is 0.52 MPa at a speed of 1 400 r/min. It is found that the HCCI combustion process of DME/CNG is characterized by a two-stage heat release process.
7.Typically, the procedure goes like this: You are hurtling in a straight line toward a corner; You apply the brakes - fully - while still travelling in a straight line; At some point, you release a little pressure from the brakes and start to turn in; As you bend into the corner and approach the throttle application point, you progressively release the rest of the pressure from the brake.
