The Electrical System Diesels require more stored energy for starting than gasoline vehicles do, especially on cold days. Instead of just using the battery to enable the starter to crank the engine, a diesel must have sufficient power to enable the glow plugs to warm the combustion chambers and then must build up enough heat and compression in the cylinders to ignite the fuel. For this reason, diesels must possess considerably more battery capacity than conventional vehicles. Some diesels come equipped with two batteries; others feature a single oversized battery that may be more than 50 percent bigger than one found on a conventional vehicle. Aside from this battery issue, electrical systems on diesels are pretty much the same as those on conventional vehicles; alternators, solenoids, and starters perform their usual functions. The Emissions System Along with much cleaner fuel, automakers are transforming the old, toxic diesels into vehicles with clean exhaust emissions by making...

Among theories advanced to explain the phenomenon, there appear to be two prevailing concepts that deal with the “ tuning ” of intake and exhaust systems. One involves the study and application of how variable pressure excursions can be used to affect volumetric efficiency (torque) throughout an engine ’ s rpm range. Commonly known as “ wave motion, ” it involves the dynamics of how specific wave events within intake and exhaust systems affect net volumetric efficiency. The other focuses on the belief that there are certain so-called “ critical mean flow velocities ” that either occur or can be deliberately created to also affect torque boosts. Interestingly, both involve piston (or cylinder) displacement, engine speed, and time, among other variables. So to say the two concepts are not related could be a misstatement. However, rather than present further arguments for either model, the subject we ’ ll address is how both can be applied in practical applications for torque gains a...

 Compact and efficient four-cylinder in-line engine generates 300 kW and 1,700 Nm of torque     The TCD 9.0 extends the upper limit of DEUTZ ’ s power range as part of a new engine platform The trade magazine OEM Off-Highway has put the DEUTZ TCD 9.0 engine in fourth place in its list of the Top Ten New Products of 2017. This prominent international publication reports on all topics related to the development of heavy-duty machinery in the off-highway sector. The rankings are based on the number of searches and page views made by users of the OEM Off-Highway Component Directory, its online purchasing resource. The TCD 9.0 four-cylinder in-line engine, which was unveiled to the world at bauma China in Shanghai, is one of four new engines from DEUTZ that mark another significant extension to the upper end of its power range. The TCD 9.0, which produces 300 kW of power and 1,700 Nm of torque, forms part of a family of engines together with the TCD 12.0 (...
