"Engines by maker" typically refers to the categorization or listing of engines according to the manufacturer (maker) that produces them. In the context of automobiles, aerospace, machinery, or other applications, different manufacturers design and manufacture various types of engines, including internal combustion engines, electric motors, and turbine engines, among others.

Piston engines, also known as internal combustion engines, are a type of engine that converts fuel into mechanical energy through the combustion process. They operate on the principle of utilizing the linear motion of pistons, which are contained within cylindrical chambers called cylinders. Here’s a basic overview of how piston engines work: 1. **Components**: Key components of a piston engine include: - **Cylinders**: Where the pistons move up and down.

Piston ported engines are a type of two-stroke engine commonly found in small applications such as chainsaws, lawn mowers, and some types of motorcycles. The term "piston ported" refers to the method of transferring air-fuel mixture into the combustion chamber through ports that are opened and closed by the movement of the piston itself.

A pistonless rotary engine is a type of internal combustion engine that operates on a rotary motion rather than the linear motion typical of traditional piston engines. One of the most well-known designs of a pistonless rotary engine is the Wankel engine, which uses a triangular rotor that spins around an eccentric housing to create chambers for intake, compression, combustion, and exhaust. **Key Features of Pistonless Rotary Engines:** 1.

"Proposed engines" could refer to a variety of contexts depending on the industry or subject matter. Here are a few interpretations: 1. **Aerospace Engineering**: In the context of aerospace, proposed engines might refer to new or conceptual designs for jet engines or rocket engines that are still in the planning or development stage but have not yet been built or tested. This could include advanced propulsion systems using new technologies.

Rocket engines are propulsion devices that utilize rocket propulsion principles to generate thrust, allowing spacecraft and missiles to lift off and maneuver in space. Unlike traditional engines that rely on atmospheric oxygen for combustion, rocket engines carry both fuel and an oxidizer, enabling them to operate in the vacuum of space.

Sleeve valve engines are a type of internal combustion engine that utilize a sleeve system instead of traditional poppet valves for controlling the intake and exhaust of gases. In these engines, the sleeves, which are cylindrical devices, slide over the openings in the cylinder walls. This design allows for a more efficient and effective method of gas exchange compared to conventional valves.

The "3,000 mile myth" refers to a common misconception about the optimal interval for oil changes in vehicles. Many people believe that motor oil needs to be changed every 3,000 miles, a guideline popularized by some quick-lube services in the past. However, advancements in engine technology and oil formulations have significantly changed this standard.

AMC computerized engine control refers to the electronic systems used in American Motors Corporation (AMC) vehicles to manage engine performance, emissions, and overall efficiency. AMC was known for several innovations in automotive technology, and as vehicles transitioned from mechanical to electronic control systems in the 1970s and 1980s, AMC incorporated computerized engine control technologies to enhance the operation of their vehicles.

The Gluhareff Pressure Jet is a specific type of jet propulsion system that was developed by the Russian engineer and inventor Alexander Gluhareff in the 1950s. This propulsion method is notable for its unique design, which incorporates a pressure jet mechanism to produce thrust. The key features of the Gluhareff Pressure Jet include: 1. **Design**: The system utilizes a combustion chamber where fuel and oxidizer are mixed and ignited, creating high-pressure gases.

A "headless engine" typically refers to a system or application that operates without a graphical user interface (GUI) or is designed to function independently of a user-facing front end. Instead of relying on a traditional interface, a headless engine interacts with users or other systems through APIs (Application Programming Interfaces), command-line interfaces, or other programmatic means.

The term "Bivalent" in the context of engines or powertrains typically refers to a type of engine that can run on two different types of fuel or energy sources. For example, a bivalent engine might be designed to operate on both gasoline and compressed natural gas (CNG), or an internal combustion engine that can run on gasoline or biofuels. The concept of bivalency is to enhance flexibility, reduce emissions, or leverage different fuel cost advantages.

Duraspark refers to a type of ignition system used in Ford vehicles, primarily during the late 1970s to the early 1980s. It is an electronic ignition system that was designed to improve starting reliability, reduce emissions, and enhance engine performance compared to traditional points-based systems. Duraspark systems often feature a module that controls ignition timing and provides a more consistent spark from the ignition coil.

Exhaust gas is the byproduct of combustion processes, typically produced by internal combustion engines, such as those found in automobiles, trucks, motorcycles, and various industrial equipment. It consists of a mixture of gases and particles that are released into the atmosphere after fuel (like gasoline or diesel) is burned in the presence of air. The primary components of exhaust gas include: 1. **Carbon Dioxide (CO2)**: A major greenhouse gas and a product of complete combustion of carbon-containing fuels.

A Carnot heat engine is a theoretical model of a heat engine that operates on the Carnot cycle, which is an idealized thermodynamic cycle. The concept was named after the French physicist Sadi Carnot, who established fundamental principles of thermodynamics in the 19th century.

A hybrid vehicle is a type of automobile that combines two or more different power sources to move the vehicle. Typically, this involves the integration of an internal combustion engine (ICE) with one or more electric motors. The primary aim of hybrid technology is to improve fuel efficiency, reduce emissions, and enhance the overall performance of the vehicle.

Alice Leigh-Smith is a relatively lesser-known figure, and there may be multiple people with that name. Without specific context, it’s challenging to provide accurate information.

Cecil Reginald Burch does not appear to be a widely recognized figure or concept based on the information available up to October 2023. It's possible that he could be a private individual, a historical figure with limited public documentation, or perhaps a character in a specific work of fiction.

An exoskeletal engine typically refers to a type of robotic exoskeleton that is designed to enhance human capabilities. These systems often utilize a combination of mechanical structures and motors to provide support and amplify the user's strength and endurance. Exoskeletons are commonly used in various fields, such as rehabilitation, industrial labor, and military applications.

A free-piston engine is a type of internal combustion engine that operates without a conventional mechanical linkage between the pistons and a crankshaft. Instead of using a crankshaft to convert the linear motion of the pistons into rotational motion, a free-piston engine relies on the pistons moving freely within a cylinder, typically driven by the pressure generated during combustion.
