Abstract
Embodiments disclosed herein relate to internal combustion engines, combustion systems that include such internal combustion engines, and controls for controlling operation of the combustion engine. The internal combustion engine may include one or more mechanisms for injecting fuel, air, fuel-air mixture, or combinations thereof directly into one or more cylinders, and controls may operate or direct operation of such mechanisms.
Claims17
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.
A combustion engine, comprising:
- an engine block including one or more cylinders therein;
- a crankshaft rotatably secured to the engine block;
- one or more pistons movably positioned in the one or more cylinders and operably connected to the crankshaft;
- one or more oxidizer injection ports unobstructedly opening into corresponding ones of the one or more cylinders;
- one or more oxidizer injectors positioned in corresponding ones of the one or more oxidizer injection ports and configured to inject an oxidizer into the corresponding one or more cylinders;
- 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;
- and
- 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;
- 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.
An internal combustion engine comprising fuel injectors for injecting fuel directly into one or more cylinders of the internal combustion engine, oxidizer injectors for injecting an oxidizer directly into the one or more cylinders of the internal combustion engine, one or more exhaust ports from corresponding ones of the one or more cylinders, one or more fuel sensors secured to one or more fuel lines of the internal combustion engine to detect at least a type of the fuel or the amount of ethanol in the fuel configured to detect at least the type of the fuel, each of the one or more exhaust ports leading to an exhaust valve which controls the flow of exhaust gases from the corresponding cylinder of the one or more cylinders, wherein the type of the fuel includes one or more of gasoline, diesel, liquefied natural gas, liquefied petroleum gas, or hydrogen.
