A crucial segment of the global economy is the marine industry. It is responsible for carrying trade around the world. According to sources, the shipping industry alone takes 80% of the global trade volume and 70% of the trade value. Naturally, marine commercial engines play a critical role in the shipping and transportation industries by powering the backbone of international trade.
To meet the ever-evolving needs of the industry, the best manufacturers produce marine commercial engines that are not only highly efficient but also comply with the latest emission norms. Since these large vessels carry tonnes of load at a time, they need engines that can generate high power to propel them across waters. New-age marine engines by Weichai are designed to operate in a demanding environment that requires reliability, efficiency, and durability. In this blog, let us dive into the role that these engines play in shaping several industries.
In the maritime industry, marine engines are used in a variety of vessels with cargo ships, tankers, container ships, and passenger ships being among the few. These engines are often large and powerful, with some engines producing over 100,000 horsepower. Marine commercial engines are available in different models with a broad horsepower range to suit different vessel sizes and applications. These engines are designed to produce more torque, which makes them ideal for marine applications. With high compression ratios and improved fuel injection systems, these marine engines are able to produce more power than before.
With the emerging crisis of renewable sources of power, the need for fuel-efficient engines is more than ever. Marine engines typically run on diesel and have a higher compression ratio and produce more power. Further, these engines operate using a compression ignition mechanism which heats the combustion chamber before the fuel enters, causing a much faster combustion process and no fuel wastage. Besides, marine commercial engines by Weichai are integrated with Electronic Control Unit or ECU which tunes the fuel injection and minimises wastage, and improves efficiency. In addition, diesel is a fuel that has a higher energy content that gets more work done as compared to other fuel sources.
Since marine environments can be harsh, engines are prone to be with exposure to saltwater, humidity, and extreme temperatures. Marine propulsion engines by reliable manufacturers are designed to withstand these challenging conditions and have a longer lifespan. The durability of diesel engines is achieved through the use of heavy-duty materials that can resist corrosion and wear. Additionally, high-quality marine commercial engines require less maintenance compared to gasoline engines, reducing the risk of downtime and increasing the reliability of the vessel.
Certain marine vessels carry flammable products which may pose a threat to the safety of crew and carriage. Sometimes, it is the fuel that can be further added to the flammability. In such cases, marine commercial engines running on diesel make a safer option for marine applications. Diesel engines have lower emissions of volatile organic compounds which reduces the risk of fire and explosion on board the vessel. As mentioned before, this becomes important for passenger ships and other vessels that carry people, as well as for commercial vessels that transport hazardous materials.
Engine manufacturers have been focusing on producing engines that are more environmentally friendly by implementing advanced technologies such as selective catalytic reduction (SCR), exhaust gas recirculation (EGR), and diesel particulate filters (DPF). These technologies help to reduce emissions of harmful pollutants like nitrogen oxides (NOx), particulate matter (PM), and sulfur oxides (SOx). The latest marine commercial engines are designed with these features and emit significantly fewer emissions than older engines.
Diesel engines have always been a popular choice for powering marine vessels for many years. These engines are designed to operate in harsh and demanding environments that require high levels of reliability, efficiency, and durability.
Weichai offers high-speed marine diesel engines that have an extremely well build design. With a broad range of HP (95-550) in different models, these engines come with mechanical pumps and electrical systems, ensuring top-notch performance and enhanced efficiency. The reliability and trust established by manufacturers like Weichai have been crucial in massively shifting the face of several industries.
