“…W ciągu ostatnich kliku lat nastąpiło znaczne ograniczenie emisji dwutlenku węgla z pojazdów osobowych sprzedawanych w Unii Europejskiej. Przyczynia się do tego downsizing silników spalinowych (ograniczenie objętości silników przy zachowaniu tych samych lub zwiększonych parametrów ich pracy, zwiększenie udziału silników o zasilaniu paliwami alternatywnymi oraz zwiększenie udziału pojazdów o napędzie alternatywnym, w tym elektrycznym) [1,14,16].…”

“…Obecnie możliwe jest wyróżnienie dwóch typów downsizingu: statycznego lub dynamicznego [1,14,16]. Pierwszy z nich polega na zmniejszeniu wymiarów silnika przez ograniczenie objętości skokowej (realizowanej przez zmniejszenie liczby cylindrów).…”

“…Currently there can be distinguish two types of downsizing: static or dynamic [1,14,16]. The first one involves reduction of engine dimensions by reducing engine displacement (through reduction of the number of cylinders).…”

“…Over the past few years there has been a significant reduction of carbon dioxide emissions from passenger vehicles sold in the European Union. The reason contributing to this is the process of downsizing of combustion engines (reduction of engine displacement while maintaining the same or increased operating parameters, increase in the share of engines fueled with alternative fuels and increase in the share of alternative-powered vehicles, including electric) [1,14,16].…”

“…Przewiduje się, że tendencje do ograniczania liczby cylindrów będą coraz większe, gdyż prognozy zwiększenia produkcji silników 2-i 3-cylindrowych wskazują na ich największą intensywność przyrostu. Z analiz firm IHS Automotie oraz BorgWarner [16] wynika, że roczne zwiększanie liczby tych silników będzie wynosiło 14% (rys. 1).…”

The article presents the possibility of reduction of the CO2 emission due to application of downsizing, resulting also in the reduction in fuel consumption by engines. From 2015, carbon dioxide emissions will be limited to 130 g/km. Due to this there has been observed an increase in the number of three-cylinder combustion engines on the offer of most global automotive companies. In the article are presented selected new designs of three-cylinder engines, with focus on their performance parameters. The static and dynamic downsizing has been defined as the contemporary direction of the development of combustion engines. In the article are also suggested indexes of static and dynamic downsizing and their interdependency for the considered combustion engines.

İçten yanmalı motorların icadı ile birlikte aynı hacimden daha fazla güç elde etmek, ortaya çıkan araştırma konularından biri olmuştur. Aşırı doldurma sistemlerinden biri olarak turboşarj, motorun yanma odasına gönderilen hava miktarını arttırarak motordan daha fazla güç elde edilmesini amaçlamaktadır. Turboşarj komplesi türbin ve kompresör olmak üzere 2 temel bileşenden oluşmaktadır. Yanma sonucu oluşan egzoz gazlarının enerjisini, motora giren havayı sıkıştırmak için kullanan turboşarj sistemi, ortak bir şaft aracılığı ile motora giren havayı sıkıştırır. Basınçlanan ve sıkışan hava, yanma odasına iletilir ve böylece aynı hacme daha yoğun hava gönderilmiş olur. Bu çalışmada standart dizel yakıtı ile çalıştırılan, dört zamanlı, altı silindirli ve su soğutmalı dizel bir motorun, turbo tahliye basıncı ayarlanarak farklı turboşaft hızlarında motor performans değerleri ölçülmüştür. Motor tam yükte ve 1000, 1500 ve 1800 d/dak motor hızlarında iken farklı turboşaft hızlarının, motor gücüne, torkuna, silindir içi basınçlara, fren özgül yakıt tüketimine, egzoz manifold sıcaklığına ve emisyonlara (İs, NOx, CO ve HC) etkileri deneysel olarak incelenmiştir. Yapılan çalışmada, motor tam yük ve 1500 d/dak’da iken turboşaft hızı artışının motor tork ve gücünü doğru orantılı olarak artırdığı görülmüştür. Turboşarj hızı arttıkça is, CO ve NOx emisyonları azalmış, HC emisyonu ise artmıştır. Motor tam yük ve 1500 d/dak’da iken tahliye basıncının 2,6 bar seviyesine ayarlanması, egzoz manifoldu sıcaklığını aşırı arttırmış ve güvenli bölgenin dışına çıkılmıştır.
