Jonas Hesselman
Jonas Hesselman (9 April 1877- 20 December 1957) was a Swedish engineer. He built the first spark ignition engine with direct injection of fuel into the cylinder. Biography Knut Jonas Elias Hesselman was born at Å församling in Östergötland, Sweden. He was the son of factory owner Bror August Hesselman and Marie Louise Hesselman, née Åberg. He was the brother of professor Henrik Hesselman (1874–1943) and linguist Bengt Hesselman (1875–1952). Hesselman graduated in 1899 from KTH Royal Institute of Technology, Department of Mechanics. He worked from 1899 to 1916 for AB Diesel Engines (later Atlas Diesel, now Atlas Copco) in Sickla in Nacka just outside Stockholm, from 1901 as Head of Construction. Here he also developed Rudolf Diesel's engine further and won international recognition as an authority on diesel engines. In 1916 he opened his own factory and in 1925 presented the Hesselman engine, a hybrid between an Otto engine and diesel engine. Jonas Hes ...

Hesselman Engine
The Hesselman engine is a hybrid between a petrol engine and a Diesel engine. It was designed and introduced in 1925 by Sweden, Swedish engineer Jonas Hesselman (1877-1957). It represented the first use of direct Gasoline direct injection, gasoline injection on a spark-ignition engine used to power a road going vehicle. Hesselman engines saw use in heavy trucks and buses in models produced in the 1920s and 1930s. Operation The Hesselman engine incorporates a combustion process with regular intake air compression. The fuel is Gasoline direct injection, direct-injected into the combustion chamber at the very end of the compression stroke, near top dead centre (TDC). Due to low compression, the inhomogeneous air-fuel mixture must be ignited by a spark plug. Under full load, Hesselman engine uses quality torque controlling without throttling, whilst under medium load and when idling, a throttle valve ensures a stable engine speed. Injection duration can be manipulated to adapt t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From Östergötland
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
