What are the characteristics of cat engine series A, B and C? Invite interested friends to attend!

Caterpillar marine power system has been innovated again on the basis of its popular Caterpillar 3500 series marine engines. The performance of Caterpillar 3500 engine is in the leading position in the market within its power range, and it has set an impressive sales record in the ship market. The latest research and development achievements of 3500C series engines have greatly reduced engine emissions, improved its output power, and enabled operators to experience stronger traction, reserve and acceleration. Caterpillar 3500C series marine engines are designed with 8 cylinders, 12 cylinders and 16 cylinders respectively, which meet the emission requirements of the US EPA marine engine Tier 2, and the power range is 578 kW-2525 kW. The perfect combination of power, fuel efficiency and reliability of the Carter 3500C engine makes it the first choice for working boats, patrol boats, port tugboats, fast ferries, coastal freighters and yachts. In the past five years, major shipyards and operators have fully trusted the Carter 3500B-HD engine. According to the results of the third quarter of 2006, in most applications, the demand for larger 3500 and 3600 series engines has increased significantly and continues to hit a record high. The delivery of 3500 and 3600 engines has increased by more than 50%. In addition, Caterpillar also invested in manufacturing and supply chain capabilities to further increase the production of 3500 and 3600 engines in 2007 and 2008. Caterpillar recently announced the launch of a 3500C engine that meets the Tier 2 emission requirements of the EPA marine engine in the United States. See the following table 1 and table 2 for details. The new hardware and software design makes the advanced engine have similar fuel consumption to the existing products. Compared with most other engines of the same class, it reduces the maintenance cost while maintaining the long service life of the engine. This is extremely important for the inland river tugboat and port tugboat market, because the new engine class improves the traction of the bollard and reduces the space occupied by the engine. All levels have passed the certification of Classification Society (MCS) and International Maritime Organization (IMO). These new engines also have excellent reserve power capability, which can provide rapid response and acceleration when needed. The newly updated control equipment and monitoring software functions will become the standard configuration of these engines. In addition, optional accessories will be provided, such as Carter plate heat exchanger installed on the engine, seawater pump and alternator driven by the engine, and large-capacity strong core air filter, which has twice the dust holding capacity of the previous filter. "Last year, Caterpillar upgraded the 3500B-HD series engine with the speed of 1600 rpm and created the 3500C-HD series engine with the speed of 1800 rpm. Now, in 2007, we repeated this practice and introduced new heavy-duty 2250 bhp and 3000 bhp B series engines with lower emissions and narrower engine shapes, "said Vikas Gaur, Product Definition Manager of Caterpillar Marine Power System in lafayette, Indiana, USA. In addition, after development, the new grade products can be used with 600/690 V 60 Hz diesel-electric propulsion (DEP) components, and can be used for 400/440 V 60 Hz marine auxiliary generator sets. The rated power is increased by 25% to 1700 ekW (35 12C-HD) and 23% to 2250 ekW (35 16C-HD) respectively. Caterpillar ACERTTM technology uses components of Caterpillar ACERTTM technology in the 3500C-HD engine, which can achieve extra power and excellent fuel saving effect. These engines use some new hardware, including optimized injector injection angle and combustion chamber, high-efficiency turbocharger, A3 ECU (electronic control unit), drilling connecting rod and high-flow piston cooling nozzle. For 16 cylinder high-power engine, the combination of modular pulse exhaust manifold and wastegate valve can bring the best turbocharging efficiency. Manifold can store the energy of exhaust pulse, so that the engine turbocharger can achieve the highest thermal efficiency. The wastegate valve provides excellent acceleration performance at low speed and medium speed. "Because of its recent rating increase and low emission capacity, the Carter 3500C ACERT engine is used to expand the application range of the 3500 engine series", Gaur stressed, "The biggest advantage of this reliable and practical propulsion engine is to minimize engine installation changes and improve the power-to-weight ratio, thus having more opportunities to equip ships".
