TLDR
In this paper, a diesel engine is adapted to operate in a conventional diesel combustion mode within a first speed and load range, and in a homogeneous charge compression ignition mode in a second load and speed range.Abstract:
A diesel engine is adapted to operate in a conventional diesel combustion mode within a first speed and load range, and in a homogeneous charge compression ignition mode in a second load and speed range. When operating in the homogeneous charge compression ignition mode, the emissions are dramatically reduced, resulting in a significant net reduction in emissions over the total load and speed operating range of the engine.read more

TL;DR: In this article, a multi-mode internal combustion engine and method of operating the engine is provided which is capable of operating in a variety of modes based on engine operating conditions to enhance fuel efficiency and reduce emissions.
Patent
Power generation system and method
TL;DR: In this article, the power generation system and method of the present invention employ a solid oxide fuel cell which reformulates fuel to a degree which is controlled by the amount of fuel introduced to the fuel cell, and the effluent is directed through a heat exchanger and then into an engine.
Patent
Internal combustion engine and working cycle
TL;DR: In this article, a method for deriving mechanical work from a combustion gas in internal combustion engines and reciprocating internal combustion engine is described. But the method is not suitable for the case of large-scale combustion engines.

Hybrid step combustion system
TL;DR: Hybrid step combustion system (HYSCOM) is available for four-stroke and two-stroke internal combustion engines as mentioned in this paper, which uses diesel and gasoline as fuels in operation.
Patent
Stratiform charging engine
TL;DR: In this paper, the authors proposed to obtain excellent combustibility and improve exhaust gas purifying performance by performing at a light load, a stratiform combustion by the supply of unevenly distributed fuel to the vicinity of the ignition device, at a heavy load range, and in a deceleration operation by throttling the suction air.
Patent
Starting fuel system for engine
TL;DR: In this article, a two-cycle crankcase compression fuel injected internal combustion engine is described, and the engine components are laid out in such a way that the spark plugs of the engine and the fuel injector will each be exposed to unobstructed air flow for cooling.
Patent
Stratified-mixture supplied engine
TL;DR: In this paper, the authors propose to switch from high-output operation of an engine without accompanying generation of smoke, by varying the switching point for switching the mode of combustion from stratified combustion to homogeneous combustion according to the density of intake air.
Patent
Stratified charging engine
TL;DR: In this paper, the condition of an engine to be early warmed so as to obtain good performance of purifying its exhaust, by performing lean state stratified combustion in a range when the engine is low loaded while uniform combustion in range when it is high loaded while decreasing an intake air amount to generate rich air-fuel ratio.
