用于机动车的内燃机
摘要：
本发明涉及一种用于机动车的内燃机(1)，带有包括燃烧室(3)的至少一个汽缸(2)，带有新鲜空气供给装置(4)，用于将新鲜空气(6)供给到燃烧室(3)中，带有废气排出装置(5)，用于将在燃烧室(3)内产生的废气(7)排出，带有废气再循环装置(8)，其与新鲜空气供给装置(4)和废气排出装置(5)流体连通，带有热交换器(40)，布置在废气再循环装置(8)中，该热交换器包括至少一个第一流体路径(42a)，待再循环的废气(7)流过该第一流体路径，并且该热交换器包括至少一个第二流体路径(42b)，燃料(15)流过与第一流体路径(42a)流体分离的第二流体路径，其中，热交换器(40)的该至少一个第二流体路径(42b)与内燃机的至少一个燃料喷射器(30)流体连通，用于将具有较高爆震数的燃料(15)引入到该至少一个燃烧室(3)中。
摘要（英）：

The invention relates to an internal combustion engine (1) for a motor vehicle. The internal combustion engine is provided with: at least one cylinder (2) having a combustion chamber (3); a fresh airsupply device (4) which supplies fresh air (6) to the combustion chamber (3); a waste gas discharge apparatus (5) which discharges waste gas (7) produced in the combustion chamber (3); a waste gas recycling apparatus (8) which is communicated through the fresh air supply device (4) and the waste gas discharge apparatus (5) through a fluid; a heat exchanger (40), which is arranged in the waste gasrecycling apparatus (8) and includes at least one first fluid path (42a), wherein waste gas (7) awiting recycling flows through the first fluid path, the heat exchanger also includes at least one second fluid path (42b), so that fuel (15) flows through the second fluid path being separated from the first fluid path (42a). The second fluid path (42b) of the heat exchanger (40) is communicated withat least one fuel jet device (30) in the internal combustion engine (1), so as to feeding fuel (15) having high knocking number into the at least one combustion chamber (3).
