| HS{Lord Ernest Hives - Chair}/ACL/AD5.11.29. contd. -2- needle taper. Now we have shewn that the power output is good we are working on the metering problem i.e. the right combination of needle taper, diffuser air piston spring. We aim first of all at getting this reasonable and then testing on a car. Afterwards when we have an idea of the snap opening up and acceleration we can continue developments on the test bed. We will give a further report when we have progressed with these tests. The figures given in this report are with open exhaust. HS{Lord Ernest Hives - Chair}/ACL. | ||
