GM Fuel Ethyl Gas Aims For 60 MPG In Ten Years
General Motors Chemical Company led by C. I. Kettering reports a new Ethyl Gas fuel blending ordinary gasoline with Ethyl Fluid. After extensive testing across GM Research Laboratories and thousands of miles driven, the team selected a colorless to wine colored liquid as the final, commercially practical fuel option.

Understanding the Ethyl Gas Discovery by GM Engineers
General Motors engineers investigated engine knocking and, through Thomas Midgley Jr.’s research as general manager of the Ethyl Gas chemical company, concluded that knocking stems from high compression rather than faulty ignition or preignition by carbon.

Wave Impact Threat to Combustion Chamber and Piston
A high velocity shock wave could strike the combustion chamber side or piston top causing extensive damage and potentially wrecking the engine.
Ethyl Gas Boosts Engine Power and Efficiency
General Motors engineers report Ethyl Gas as a fuel additive to raise compression and prevent knocking. Adding one tenth of one percent Ethyl Fluid to gasoline is claimed to restore power, reduce gasoline waste, and cut carbonization, aligning with Kettering’s 50 miles per gallon forecast.

Brake system faults and remedies in older vehicles
It stresses keeping brakes in working order and explains causes of brake failure. Slippage may come from oil inside drums or worn linings, and binding from too loose an adjustment. It notes oil from the rear axle can contaminate brake bands and suggests washing with gasoline as a fix.
Checking Valve Timing In Automotive Engines
The article explains how improper valve timing causes wear and slipping in linings and brakes. It outlines a rule: late opening and early closing mean excessive clearance, while early opening with early or late closing signals incorrect timing gear meshing.
Testing Compression and Spark to Diagnose Spark Plug Fouling
To diagnose a badly fouled spark plug, first test the cylinder compression to confirm valve function. Then check ignition by holding the spark plug wire a quarter inch from the plug terminal while the engine runs, noting shocks as a warning but using this method as the only reliable ignition test.
Importance of steering maintenance in motor cars
The steering gear, part of the steering system, is constantly in motion reacting to depressions and irregularities in the road. Even when driving straight, the steering linkage and rear steering components adjust continually, making this unit a vital control element of the car.
Valve Spring Compressor Lets Two Springs Be Simultaneously Compressed
A homemade tool uses flat stock slots to fit over two pushrods and valve stems. A drilled center holds a stud riveted to prevent turning. A nut on the stud raises the upper piece to compress both springs at once. The setup stays in place while grinding the valves.
Test Valves for Warpage Automotive Digest
Warped valves due to extreme heat in the combustion chamber can prevent perfect seating. The only reliable test is to remove the valve and inspect it. Place the valve upright and measure head to stem end at several points with a ruler. uniform measurements mean no warp. If warped, replace the valve.
