1. A combustion engine, comprising:
one or more combustion chambers;
one or more conversion mechanisms each located in corresponding ones of the one or more combustion chambers, and each of the one or more conversion mechanisms being configured to convert a pressure increase in the combustion chamber into one or more of rotation of an output shaft or a linear movement of a linear output mechanism;
one or more oxidizer injectors operably connected to a supply of an oxidizer and configured to inject the oxidizer into corresponding ones of the one or more combustion chambers;
one or more fuel injectors configured to inject the fuel directly into the one or more combustion chambers;
one or more fuel lines operably connecting the one or more fuel injectors to a supply of fuel;
one or more fuel sensors configured to detect at least a type of the fuel, the one or more fuel sensors being secured to the one or more fuel lines to detect at least the type of the fuel, wherein the type of the fuel includes one or more of gasoline, diesel, liquefied natural gas, liquefied petroleum gas, or hydrogen;
one or more air lines in fluid communication with the one or more oxidizer injectors and with a source of compressed oxidizer;
an intake manifold connected to the one or more air lines, the intake manifold being sized and configured to distribute compressed oxidizer among the one or more air lines;
a compressor operably connected to the intake manifold, the compressor being configured to compress a gaseous oxidizer;
an air pressure regulator configured to regulate the pressure between the compressor and the intake manifold, wherein the air pressure regulator is automatically adjustable to a predetermined pressure during operation of the combustion engine;
a first air pressure sensor between the compressor and the air pressure regulator, the first air pressure sensor configured to detect output air pressure of the air compressor; and
a second air pressure sensor between the air pressure regulator and the intake manifold, the second air pressure sensor configured to detect air pressure in the intake manifold.
