Abstract
Abstract A steam generating tube is mounted in the exhaust manifold of the engine and supplied with water from a water tank. Wet steam generated in the tube passes through a steam separator and substantially dry steam is injected into the intake manifold of the engine to pass into the cylinders along with the fuel and air mixture from the carburetor. Water removed from the steam in the steam separator returns to the tank. The steam separator comprises a housing filled with stainless steel shavings, one end of said steam generating tube being connected with said housing. A tube to a steam control valve is connected to the top of said housing and a water return tube in the bottom of said housing is connected with said tank.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
155 words
A steam injection device for an internal combustion engine comprising a steam generating tube mounted in the exhaust manifold of the engine, a water tank supplying water to said tube, a steam injector fitting in the intake manifold of the engine, means connecting said steam generating tube with said injector fitting including a steam control valve, means connecting said valve with the engine throttle valve linkage arranged to open said steam valve as said throttle valve is opened, a steam separator arranged to separate any free water from the steam received from said steam generating tube and return said water to said tank, said steam separator comprising a housing filled with stainless steel shavings, one end of said steam generating tube being connected with said housing, a tube to said steam control valve connected to the top of said housing, and a water return tube in the bottom of said housing connected with said tank.
Claim 2
Dependent Claim

Claim 4
Dependent Claim
24 words
A device as defined in claim 1, said tank comprising a pair of flanged opposite end sections secured together by bolts in said flanges.
Claim 5
Dependent Claim
135 words
A steam injection device for an internal combustion engine comprising a pair of bushings in the exhaust manifold of the engine, a steam generating tube in said manifold mounted in said bushings, a water tank, a lower end of said tube being connected to the bottom of said tank, a steam separator connected to the upper end of said tube, a water return tube connected between the bottom of said separator and said tank, a steam control valve operable by the throttle linkage of the engine, a steam tube connected between the top of said separator and the inlet of said valve, a steam injector fitting in the intake manifold of the engine, a steam tube connected between said injector fitting and the outlet of said valve, and a vented filler plug in said tank.
