The internal combustion engines operating in the four-stroke cycle are most widely used on all types vessels with different purpose. Mostly, the vessels use medium and high-speed engines of this type, however, a number of Asian manufacturers produce low-speed four-stroke engines which are capable to operate with direct power transmission to the ...

SAE Technical Paper Series, 1988
<div class="htmlview paragraph">A new type of variable-stroke engine, or compressor, is presented in this paper. The stroke is adjusted by changing the length of the ground link using an auxiliary mechanism. Adjusting the ground link, changes the rotation angle and the effective length of the connecting rod, which in turn controls the pumping ...

Comparison of Four Stroke MotoGP Engines
SAE Technical Paper Series, 2004<div class="htmlview paragraph">This paper compares different engine solutions for the FIM MotoGP World Championship. Starting from the general guidelines given in a previous paper [<span class="xref">2</span>], in this study the specific features of each engine architecture (3 and 4 in line, V4, V5 and V6) are considered.

The absence of the separate induction and exhaust strokes in the two-stroke engine is the fundamental difference from four-stroke engines. In two-stroke engines, the gas exchange or scavenging process can have the induction and exhaust processes occurring simultaneously.

The basic two-stroke cycle was described in Chapter 1 and the operation of this type of engine can now be amplified. Fig. 12.1 shows a typical indicator diagram for a two-stroke, and it can be seen that because the ports open during the stroke the compression and expansion phases are restricted.

Scavenging the 2-Stroke Engine
SAE Technical Paper Series, 1954<div class="section abstract"><div class="htmlview paragraph">THE indicated output of a 2-stroke engine is primarily dependent upon the success with which the products of combustion are driven from the cylinder and are replaced by fresh air or mixture during the scavenging period.

Conventional two‐stroke engine lubrication
Industrial Lubrication and Tribology, 1997Gives the results of trials conducted in China which show the use of top‐grade, low smoke, part synthetic two‐stroke oil gives better performance and four times longer engine life than the four‐stroke engine oils generally used to lubricate two‐stroke engines in China. Sets out existing and proposed international standards for two‐stroke engine oils.

<div class="section abstract"><div class="htmlview paragraph">The purpose of this paper is to describe a novel liquid fuel conditioning process that is incorporated within a 4-stroke internal combustion engine. The process takes place inside a small external vaporization chamber linked to the engine cylinder. A vaporization chamber transfer

Novel Two-Stroke Engine Concept, Feasibility Study
SAE Technical Paper Series, 2003<div class="htmlview paragraph">A novel two-stroke engine concept is introduced. The cylinder scavenging takes place during the upward motion of the piston. The gas exchange valves are similar to typical four-stroke valves, but the intake valves are smaller and lighter. The scavenging air pressure is remarkably higher than in present-day engines.

Endogenous regeneration: Engineering growth factors for stroke
Neurochemistry International, 2017Despite the efforts in developing therapeutics for stroke, recombinant tissue plasminogen activator (rtPA) remains the only FDA approved drug for ischemic stroke. Regenerative medicine targeting endogenous growth factors has drawn much interest in the clinical field as it provides potential restoration for the damaged brain tissue without being limited
