Start-up Eco-Motive developing dual-fuel “H” engine; parallel, independently fueled piston banks

Green Car Congress

The H-engine—basically two separate engines housed within the same engine block—comprises two switchable parallel piston banks, independently fueled by gasoline and CNG. Startup Eco-Motive has developed what it calls the first dual-fuel “H” engine; it recently received a patent (# 8807098 ) on the design.

Scuderi Releases Video Footage of Running Split-Cycle 1L Prototype

Green Car Congress

Scuderi Group, LLC has released the first video footage (with sound) of its split-cycle Scuderi Engine prototype running, on its own, in the laboratory test cell. Split-cycle engines separate the four strokes of intake, compression, power, and exhaust into two separate but paired cylinders. The Scuderi Engine.

Grail Engine Adopts Enerpulse Pulse Plugs for Forced Semi-Homogeneous Charged Compression Ignition in Concept Two-Stroke Engine

Green Car Congress

HCCI is a combustion regime in which well-mixed fuel, exhaust gas and air are compressed to the point of auto-ignition. Unlike a spark ignition gas engine or diesel engine, HCCI produces a low-temperature, flameless release of energy throughout the entire combustion chamber.

Concept: Downsized and Supercharged Hybrid Pneumatic Engine for 30%+ Reduction in Fuel Consumption

Green Car Congress

The HPE was long thought to be a system in which all engine valves had to be actuated in a fully variable manner to allow for two-stoke pneumatic modes and still enable the four-stroke combustion mode. In large naturally-aspirated SI engine, high-friction, pumping losses and part-load operation all contribute to poor fuel efficiency.

Scuderi Group Unveils Cutaway Model of First Production Prototype of Split Cycle Engine

Green Car Congress

The engine cutaway is an exact duplicate of the prototype undergoing testing and analysis by SwRI in San Antonio, Texas. Subsequent implementation of the Split Cycle will be a turbocharged split cycle unit, an air hybrid version of the engine, and a diesel-fueled version. Tags: Concept Engines. Sal Scuderi.
