90 years ago, Germany's first diesel direct injection engine truck was born. On March 12, 1924, two engineers from Mann, Germany, Sturm and Wiebicke set out from the factory in Augsburg and drove the MAN Saurer truck to Nuremberg. This is a 4-ton flatbed truck, and its engine was being used for a major test at that time: diesel direct injection technology was tested in a four-cylinder engine. About 40 horsepower output, the tester needed to drive the 4-ton flat-bed truck equipped with this engine to complete the 140 km drive test in 5 and a half hours. The successful invention of this engine technology has become another milestone in the history of the engine and will mean that compact, economical and reliable diesel engines are used in motor vehicles. Bernd Maierhofer, a member of the Executive Board of the German Man Development Group, said: "The German diesel direct injection engine technology is a milestone in the history of engine technology. You can still see its huge impact today: whether it is applied to cars or trucks. The diesel engines are all based on the principle of direct injection. The latest typical application is common rail technology. We apply this technology to all German MAN diesel engines, so that we can more effectively control the combustion process in the cylinder. "" The debut at the Berlin Motor Show in 1924 sparked intense attention from the industry At the Berlin Motor Show on December 10-18, 1924, German Man demonstrated this advanced technology. Prior to this, the MAN Saurer truck had traveled 2,500 kilometers. Engineer Sturm insisted on driving the truck to the Berlin Exhibition Center. The journey from Nuremberg to Berlin took two days and the car did not have any problems during the entire journey. When the engineer Sturm reached the finish line, he telegraphed his colleagues in Augsburg with a "full success" to describe the trip. This left a deep impression on the public and the automotive media. The German Institute of Engineers magazine published a related comment: "In the truck engine and related fuel fields, the German compressorless diesel engine is undoubtedly the most significant innovation ever seen at the show." So far, this advanced engine Also displayed at the German Museum. The successful exhibition at the Berlin Motor Show established a good start for the mass production of the new series of D 1580 B diesel engines. German Mann also began producing diesel engines for commercial vehicles. The first customers, Kraftverkehr Bayern and Reichspost, bought the vehicle with a trial attitude. The truck was first used at the "zum Hasen" brewery in Augsburg. This "Beer Truck" has been operating in Augsburg for several decades with its outstanding performance. There was no major problem during the whole process of use. In 1925, the first passenger car equipped with a diesel direct injection engine was purchased by Reichspost. All engineers in Germany have spared no effort to carry out technological innovations. Today's German Mann has the world's leading commercial vehicle technology with products all over the world.
The Convector heater warm the room as it passes over a heated coil; some use a fan to forced in the cool air to heat. The heated air rises naturally or is forced out by a fan and spreads into the space to warm room.
A convection heater is a type of heater that uses convection currents to heat and circulate air. These currents circulate throughout the body of the appliance and across its heating element.
Convector heater including glass convection heater, Metal Convection Heater, also mini convector heater can be a Frost Heater.
