MAPP is colorless in both liquid and gas form. The gas has a pronounced acetylene-like or fishy odor at concentrations above 100 ppm, due to the addition of substituted amines as a polymerization inhibitor. Low molecular weight alkynes have strong odors. MAPP gas is toxic if inhaled at high concentrations. Mapp gas is a mixture of various hydrocarbons, principally, methylacetylene , propadiene and Propane(MAPP). It produces a relatively hot flame (2,976°C) with a high heat release in the primary lame (inner cone) (15,445kJ/m 3 ), less than for acetylene (18,890kJm 3 ) but much higher than for propane (10,433kJm 3 ). The secondary flame (outer cone) also gives off a high heat release, similar to propane and natural gas. The combination of a lower flame temperature, more distributed heat source and larger gas flows compared with acetylene results in a substantially slower pierce time.

On July 17, 2014, Nanjing Iveco's high-end light truck "Transcendence" (Shangchai Power) listing launch was held in Nanjing headquarters. This new product launch conference is the first step for deep and substantive cooperation between Nanjing Iveco and Shanghai Diesel Engine. It is also a concrete embodiment of SAIC Motor's strategy of creating a competitive power chain in the commercial vehicle sector. Yang Junhu, general manager of Nanjing Iveco Motor Company, Jiang Kai, general manager of Shanghai Diesel Co., Ltd., and dealer representatives, customer representatives and nearly one hundred media from across the country have witnessed this event.
The rapid development of the market economy and the accelerating process of urbanization have accelerated the pace of technological innovation in the automotive manufacturing industry. At the same time, energy consumption has intensified and air quality has been deteriorating, making energy conservation and emissions reduction an important issue for the world. On July 1, 2013, China formally implemented the National IV emission standard nationwide. As the heart of the automobile, the performance of the engine is often regarded as the first to judge whether a vehicle can meet the national IV or even higher emission requirements. standard. In the field of China's light commercial vehicles, Nanjing Iveco's power chain system has been in a relatively leading position. As early as the transition from State II to State III, Nanjing Iveco's technical team, consisting of European and domestic experts, set out to develop a high-speed, environmentally friendly, green engine that can achieve better emission standards. As Nanjing Iveco's first high-end light truck products in the true sense, "beyond" light truck power matching is at the forefront of the industry. Both SOFIM and F1C are fully in line with national IV emission requirements and can further meet European demand. IV standard.
Similar to the previously launched SOFIM high-pressure common-rail diesel engine, Fiat F1C country IV, and national V high-clean diesel engine, the SC28R electric control country IV engine supporting the C100 and C300 is a purely European technology originated from the Italian VM company; supporting the C500 The SC4H electronically controlled China IV engine is a new generation of energy-saving and environmentally friendly engines jointly developed by Shanghai Diesel and Ricardo. As the pioneer and leader of China's power market, Shangchai has been filling the gap in China's power sector since its design and manufacture of the first fully domestically-produced 6135 diesel engine in 1958. In early 2008, SAIC Motor's Shangchai Power was integrated into its own complete diesel product system and became an important member of SAIC's commercial vehicle core component system. This time, the two engines designed and manufactured by “Beyond†are the diesel power platforms based on the National IV standard, which are based on the Group’s commercial vehicle development strategy and product plans. The output power range of the SC28R is 82-105 KW. The SC4H's output power range is 105-132KW. The two engines have strong power, low fuel consumption, and low noise, extending and enriching the user's choice. The SOFIM and F1C engines constitute Nanjing Iveco's emission requirements for the State IV and Future V. The golden power chain combination.
Nanjing Iveco's high-end light truck "beyond" has been highly acclaimed by industry experts and users for its superior quality and service since it was listed on the global market. Not only won the title of "China Light Truck of the Year", but also won the championship in various top international auto racing events. 2013 Dongchuan International Mudstone Off-Road Rally Team Truck Champion, First China Off-Road T4 Truck Group Champion, 2014 Mohe International Snow and Ice Motors Cross-Country T4 Truck Team Champion, also won many awards in the China International Truck Fuel Contest. "The excellent performance made this honor worthy of its name.
While gaining many honors, the market performance of "Beyond" is also outstanding. At present, it has successively signed long-term strategic cooperation with Suning Cloud Merchants, Hongtusanbao, COFCO, and many urban vegetable basket projects involving people's livelihood issues. In the international market, after a year's development, "Beyond" has signed first-time export orders of 3,500 vehicles with dealer representatives from South America, Europe, the Middle East, and Southeast Asian countries and regions. The success of "beyond" in domestic and foreign markets has also laid a solid foundation for the successful completion of the 12th Five-Year Plan for commercial vehicles in the field of commercial vehicles and the sustainable development of the company.
When asked about “surpassing†the future layout for the domestic market, the person in charge of Nanjing Iveco stated that in recent years, with the acceleration of urbanization and the strengthening of policies and regulations, the demand for high-end products has also increased. It has provided a good market foundation for “surpassing†in the segmentation market, especially in the field of logistics. The Pearl River Delta, the Yangtze River Delta, and the Bohai Bay region are China's three major economic circles. "Transcendence" will be centered on this and will form a gradual radiation, and strategic deployment of the domestic market will begin. Nanjing is one of the important economic centers in the economic circle of the Yangtze River Delta, and it is also an industrial agglomeration area and logistics strategic hub in East China. Therefore, regional economic development and upgrading of urban logistics demand will directly determine “beyond†entering the relative market segments. speed.
During the IPO, more than one hundred user representatives and media reporters were invited to participate in the test drive, and experienced first-hand the new experience brought by Shangchai Power's “transcendenceâ€.
The new "Beyond" product powered by Shanghai Diesel will be used as a supplement to power output, and it will be equipped with a series of products including SOFIM and F1C to form a complete golden power chain for the entire vehicle series, fully satisfying domestic urban logistics, government and industry specialties. The need for comprehensive upgrades of vehicle emission requirements will provide users with more choices. The comprehensive launch of high-end light truck "beyond" strains will also bear the heavy responsibility of Nanjing Iveco to establish itself in the domestic market and enter the international market, and set a new milestone for China's light-card manufacturing companies.
