	Ricardo: High Tech In Sussex
		Harry Ricardo (later - much too late, in the opinion of many people - Sir Harry) was born and brought up in Shoreham and started building engines when he was a schoolboy.
		In 1986, 12 years after Sir Harry's death, Ricardo was responsible for the re-design of the Teledyne Continental engine which powered the Voyager plane on the first-ever non-stop round-the-world flight which didn't involve refuelling.
		Ricardo is emphatic that diesel technology has a very long way to go, and that few people outside the industry have any real idea of just what improvements are not only possible, but also nearly at production status, in power, torque, economy and emission levels.

	my.IS - 330 lb-ft of torque from a 2-liter, 4-cylinder engine?
		Yes, that's the insane claim made by Ricardo Engineering, which is working on an engine that gives a four cylinder the power and smoothness of an eight by changing from a four-stroke to a two-stroke on demand.
		The key to Ricardo’s variable cycle engine is its cylinder head design, specifically the inclination and location of the intake and exhaust valves.
		Sir Henry Ricardo was an automotive pioneer, I have been trying to find his book on the internal combustion engine for a while now, I have been told it is great reading, if anyone has access to it, please PM me.

	Mk V Composite (Site not responding. Last check: 2007-10-19)
		Originally the Mk V was produced in two types, a "gun-male" (intended to destroy machine-guns) and "machine-gun female" (intended to comb trenches), and later in a combined type, designated the "Composite", with one side (left or right) for cannon and the other side for machine-guns.
		Later on Mark V tanks were employed by white guards in the course of offensives on Moscow and Tsaritsyn, near Petrograd, Arkkhangelsk and in the Donets Basin, in the battles of the North Caucasus, on the Itstmus of Perekop and the Beachhead of Kakhavka, also when in invading the North Taurinda.
		The Mk V tanks captured by the Red Army were adopted by the armoured forces of the Soviet Republic and the USSR up to early in 1930 under the name of Ricardo or "B"-type ("Bolshoi", i.e., big) and constituted the backbone of the combat potential of their tank elements.

	Lister Diesel Miscellany
		Sir Harry Ricardo had served as a consultant to Listers for some time, designing combustion chambers for the petrol engines that greatly improved their power output and efficiency.
		Ricardo was well known for Diesel combustion chamber design as well, particularly for his "Comet" combustion chamber.
		I have mentioned the Ricardo Comet combustion chamber design in some detail because I believe it may have been the basis for the somewhat modified, yet strikingly similar, chamber of the CS engines.

	Feature Article - Research, Racing & Even Manufacturing Engineering - 05/01
		While there is undeniably that, the storied engineering consultancy (the story begins for it in 1905, when Sir Harry Ricardo established what was then known as "The Two-Stroke Engine Company") is a lot more than analytical investigations and exotic developments related to powertrain.
		Ricardo has worked with GM on the development of a steam-powered engine (and this was in 1972, not early in the 20th century) and more recently with Ford on its Partnership for a New Generation of Vehicles (PNGV) technology.
		Hensley admits that there has long been prototype build of engines within Ricardo—perhaps 20 per year—but what he is talking about is helping manufacturers with volume production, whether these are companies that are looking for supplemental skills to their own engine-building know-how or are companies that have never been in the engine business before.

		By incorporating an inspection “porthole,” Ricardo was able to observe the flame path inside the combustion chamber.
		The earliest motorcycle incorporating this concept is the 4-valve Triumph Ricardo of 1921.
		Along the way, Ricardo also discovered that the more iso-octane in the fuel, the more resistant it was to detonation, and developed a scale to measure detonation resistance: the octane rating.

	Ricardo, Harry Ralph - Encyclopedia of Earth
		Harry Ralph Ricardo (1885-1974) was an English engineer who played a leading role in the development of the internal-combustion engine.
		Ricardo graduated from the University of Cambridge Department of Engineering in 1906.
		His notable contributions include a patent for the two-stroke engine design, engines that would be used in the first tanks, research into the physics of internal combustion that led to the use of octane ratings, and the Diesel pre-combustion chamber that made high-speed diesel engines possible.

		Harry Ricardo built a variable compression ratio engine that led to the development of an octane rating system, better fuel refining, and ultimately, high performance aircraft fuel.
		There were limits, however, to how much pressure a given cylinder could build without spontaneous (and potentially catastrophic) combustion, and this is where Sir Harry Ricardo figured out that the addition of water mist into the cylinders would cool the intake charge and increase the detonation threshold.
		After reading about Harry Ricardo, I decided that I wanted to play with distributor advance in order to increase my Chevelle's fuel economy, among several other things I did at that time.

		The pioneering research was done by people like Sir Harry Ricardo, the researchers at NACA in Langley Field and all the aero engine designers of the period entering the Second World War.
		Sir Harry Ricardo proved once and for all that you can richen things up to a point but, beyond this, detonation is going to rear it’s head no matter how much fuel you throw at it and, in fact, the extra fuel may increase the tendency to detonate!
		As Sir Harry Ricardo stated..."By the introduction of water...the fuel/air ratio could be reduced once again; in fact, with water injection, no appreciable advantage was found from the use of an over-rich fuel/air mixture".

	Octane (Site not responding. Last check: 2007-10-19)
		The octane number came about as a result of research carried out in the 1920s and 30s by Sir Harry Ricardo ("The Internal Combustion Engine" 1925, 1935, and other books) and Charles Kettering (he also developed the distributor and coil ignition system).
		Harry Ricardo developed the concept of a test engine, in which the compression ratio, valve timing and other factors could be altered whilst the engine was running.
		Kettering assigned Thomas Midgley to investigate the problem of knocking which was destroying his test engines.

		The Harley-Davidson engineer, however, encountered several technical difficulties that he was unable to overcome; so he persuaded Walter Davidson to engage the famous English engine designer, Sir Harry Ricardo, to help him complete the new design.
		Within a few weeks of his arrival in Milwaukee, Sir Harry solved the problem with the cylinders, but the new H-D motor would not be entered in a major race until well into the 1916 season.
